Timeline: Sean Miller's career as the Arizona Wildcats' head coach

The UA announces that it has hired Miller, the former coach at Xavier, after the two sides met in Albuquerque the day before.

Miller takes over the program after long-time head coach Lute Olson retired after 25 years at the helm.

The first batch of recruits Miller hauls into Tucson set the tone for his tenure at the UA. 

Miller's first commit comes from Ukranian big man Kyryl Natyazhko. He was then followed by Kevin Parrom, Solomon Hill and Max Wiepking. The last two recruits of the class were former USC commits, point guard Lamont "Momo" Jones and power forward Derrick Williams. 

Miller's last-minute 2009 class was ranked No. 2 the Pac-12, per 247Sports.com. 

Junior power forward Jamelle Horne records a double-double with 14 points and 11 rebounds, while the backcourt in Kyle Fogg and Nic Wise combines for 25 points as the Wildcats top NAU 87-70 in McKale Center. The win is Miller's first at Arizona. 

The Wildcats defeat Oregon 90-82 to clinch the Pac-12 regular season title, the first under Miller and the UA's first since 2005. 

After winning Pac-10 Coach of the Year, Miller leads the Wildcats back to the big dance in 2011 after the Wildcats missed the tournament for the first time in 25 years.

The Cats beat Texas in Round of 32 and take down No. 1 Duke in the Sweet 16. In the Elite Eight, the Wildcats fall short after running into National Player of the Year finalist Kemba Walker and the UConn Huskies. 

The Wildcats finish third in the Pac-12 and post a 23-12 record, capped off with a 65-54 loss to Bucknell in the first round of the National Invitational Tournament.

No. 18 Arizona loses to UCLA 66-64. In the game, UCLA's Jordan Adams strips a driving Mark Lyons, but Lyons maintains possession of the ball in which he tried to pass it to a Wildcat on the perimeter. The official calls Lyons for double-dribble.

Miller tells the official "he touched the ball," saying it's a bad call.

Miller is called for a technical foul and the Wildcats go on to lose in the Pac-12 Tournament. Miller shows his emotions in the postgame press conference.

The Wildcats score 100 points and beat Fairleigh Dickinson by 50 points, giving Miller his 100th win as Arizona's head coach. 

“It feels good,” Miller says about the career milestone. “Better to celebrate that than not be at that number. Hopefully there’s many more this year and beyond.” 

On senior night, the Wildcats beat Stanford 79-66 to win the Pac-12 regular season championship, Miller's second title at Arizona. Miller then wins another conference coach of the year accolade. 

With Brandon Ashley out for the year with a broken foot, Arizona struggles to defend Wisconsin star Frank Kaminsky in the post. Kaminsky scores 28 points and grabs 11 rebounds and the Badgers topple the Cats in overtime. 

Nick Johnson has a chance to win the game on the final possession, but doesn't the get shot off in time and the Cats fall in the Elite Eight.

Arizona routs Oregon 80-52 in the Pac-12 title game, giving Miller his first-ever Pac-12 Tournament title.

Arizona gets a rematch with the top-seeded Badgers, and while Frank "The Tank" Kaminsky isn't as a big of a factor on the boards as in 2014, he still manages to score 29 points. Except this time, Sam Dekker was there to back Kaminsky up. 

Dekker drops 27 points on 5 of 6 shooting from 3-point range and for the second straight season, the Badgers are in the Final Four, not Arizona. T.J. McConnell, Stanley Johnson, Rondae Hollis-Jefferson and Brandon Ashley would leave for the NBA Draft afterwards.

Arizona beats Arizona 73-60 in Tempe and sweeps the Sun Devils for the second straight season, clinching a share of the Pac-12 regular season championship with Oregon. 

The Wildcats outlast Oregon 83-80 in the Pac-12 Tournament final behind Allonzo Trier's 23-point performance; the junior guard is named the Pac-12 Tournament's Most Valuable Player.

In the Sweet 16, the Wildcats run into his former team, Xavier. Arizona struggles in the second half, and freshman Lauri Markkanen doesn't have a shot attempt in the final 11 minutes, and the Musketeers upset Arizona 73-71. 

Arizona returns Allonzo Trier, Rawle Alkins, Parker Jackson-Cartwright, Dusan Ristic and Keanu Pinder for the 2018 season, all players that had significant roles on the 2017 Sweet 16 team.

Miller adds to that a recruiting class that inclues Ira Lee, Brandon Randolph, Alex Barcello, reclassified five-star 2018 prospect Emmanuel Akot — and No. 1 overall recruit Deandre Ayton, the 7-foot-1 Bahamian prodigy who played at Phoenix's Hillcrest Prep.

Arizona assistant coach Emanuel "Book" Richardson is arrested by the FBI on allegations of bribery after he allegedly asked for $20,000 from co-defendants Christian Dawkins and Munish Sood, and released after posting a $50,000 bond. Richardson faces up to 60 years in federal prison and $1.5 million in fines if convicted of all charges.

After nearly a week of silence, Miller releases a statement saying he's "devastated" over the allegations against Richardson.

Here's the full statement:

“I was devastated to learn last week of the allegations made against Emanuel Richardson," he said. I have expressed to both Dr. Robbins and our Athletic Director Dave Heeke that I fully support the university’s efforts to fully investigate these allegations.

"As the head basketball coach at the University of Arizona, I recognize my responsibility is not only to establish a culture of success on the basketball court and in the classroom, but as important, to promote and reinforce a culture of compliance. To the best of my ability, I have worked to demonstrate this over the past 8 years and will continue to do so as we move forward.”

On the eve of Arizona taking on Oregon in Eugene, ESPN's Mark Schlabach reports that the FBI has a wiretapped phone conversation between Miller and ASM Sports agency runner Christian Dawkins in which the two allegedly discuss a $100,000 payment to Ayton.

As a result, Miller doesn't coach the Wildcats in their overtime loss against Oregon.

Miller denies the ESPN report and announces that he plans to coach the team to a Pac-12 championship.

"I have never knowingly violated NCAA rules while serving as head coach of this great program," Miller said. "I have never paid a recruit or prospect or their family or representative to come to Arizona. I never have and I never will. I have never arranged or directed payment or any improper benefits to a recruit or prospect or their family or representative and I never will."

UA president Robert Robbins and AD Dave Heeke back Miller, releasing a joint statement saying they have no reason to believe he violated NCAA rules at the time.

After clinching the Pac-12 regular-season title in Miller's return from the ESPN fallout, Arizona wins three games in as many days in Las Vegas to win its second straight tournament championship and third in four years.

Buffalo blasts No. 4 seed Arizona in the first round of the NCAA Tournament in Boise, Idaho. The 21-point loss is the fourth-worst loss the program has suffered in tournament history, and a Miller-coached team is sent home after the first round for a second time in three seasons.

The Arizona Board of Regents approves amendments to Miller's contract that adds a $1 million penalty for wrongdoing and tighter Title IX language.

Miller stands to lose $1 million of his longevity fund shares if he is charged with a crime or found to have committed a Level I (major) NCAA violation.

Arizona Gatorade Player of the Year Nico Mannion commits to Arizona in September 2018, becoming the first recruit of the 2019-20 recruiting class. Mannion, a five-star guard out of Pinnacle High School (Phoenix), is the building block of the nation's sixth-ranked recruiting class.

It marks Miller's eighth recruiting class that ranked top 10 nationally. 

The Wildcats also sign five-star guard Josh Green, four-star forward Zeke Nnaji and three-star center Christian Koloko in the class.

After losing much of the 2018-19 recruiting class to de-commitments, Miller rebuilds Arizona's roster on the fly. The 2018-19 Wildcats are led by Brandon Williams, who recommits to UA after previously backing out of his original verbal commit. 

Arizona starts out the season 14-5 and in the hunt for an NCAA Tournament berth. But the team sputters at the end of January, losing back-to-back games to USC and UCLA.

The Cats then drop four more consecutive games, marking the first time in 35 years the program lost five or more in a row. They finish the season 17-15 and 8-10 in the Pac-12, the first time in Miller's career the team did not go over .500 in conference play.

Arizona Wildcats assistant coach Mark Phelps is removed from the bench after ESPN reported that Phelps was involved in an NCAA issue regarding the academic records of former UA commit Shareef O’Neal.

UA athletic director Dave Heeke calls an impromptu press conference during halftime of Arizona's home basketball game against Washington State to affirm he plans to keep Miller as the team's head coach. 

“We’re fully supportive of the coaching staff, the leadership of the basketball program,” Heeke said. “We’re supporting, as I have said before, we support Coach Miller. Those things that have been said to the contrary to that are not true.”

Rather than fire him, the UA allows Phelps' contract to run out.

New York judge Edgardo Ramos rules that the Arizona Wildcats’ coach and LSU coach Will Wade do not have to testify in the federal trial involving corruption in college basketball, saying their alleged misdeeds are irrelevant to the felony bribery charges facing would-be agent Christian Dawkins and Adidas rep Merl Code. 

The University of Arizona men’s basketball program confirms it is being investigated by the NCAA. UA issues a statement refuting other reports published that might have implied the investigation was new.

In the AP preseason poll, the Wildcats are ranked 21st in the country, marking the first time since 2018 that the team has been nationally ranked.

UA is also picked to finished fourth in the Pac-12 preseason poll.

A week before the season opener, Kentucky transfer Jemarl Baker is granted immediate eligibility for the 2019-20 season, boosting UA's outlook for the season to go along with a top 10 recruiting class.

Baker, a 6-foot-4-inch guard from Southern California, initially was expected to sit out the season He decided to appeal based on injuries and other issues in Lexington. 

The addition of Baker helps Arizona fill in its depth issues after sophomore guard Brandon Williams was lost for the season due to a knee injury before the start of the year.

Freshmen Nico Mannion, Josh Green and forward Zeke Nnaji combine for 62 of Arizona's 90 points in a 21-point home win over Illinois. 

Their performance leads Miller to believe it's possibly his best class at Arizona.

"It’s certainly one of the best, if not the best," he said.

No. 15 Arizona makes just 8 of 30 3-pointers and shoots under 40% as a team in an 84-80 loss to No. 6 Gonzaga in McKale Center.

Miller holds a 17-minute press conference after the game detailing why Arizona was unable to win.

The Wildcats post a 21-11 regular-season mark, peaking in March.

In the first round of Pac-12 tournament on March 11, the Cats beat Washington 77-70 behind Josh Green's 19 points to set up a match with USC in the quarterfinals. 

Miller calls it "one of our season’s best performances."

A day later, the Pac-12 and NCAA tournaments are canceled because of the coronavirus pandemic.  12, the coronavirus is declared a pandemic in the United States and both the Pac-12 and NCAA tournaments were canceled, effectively ending Arizona's season.

At the time, UA hovered between a 6 or 7 seed.

Arizona is charged with nine rules violations in the NCAA's Notice of Allegations, five of which are Level 1 violations.

Miller is charged with a Level 1 violation for a lack of head coach control and failing to monitor two assistant coaches accused of academic misconduct and improper recruiting inducements. The NOA is not released to the public until the following March.

“I understand and fully support the university’s decision to self-impose a one-year postseason ban on our men’s basketball program," Miller says in a statement. "Our team will remain united and aggressively compete to win a Pac-12 championship.”

Arizona is outscored 44-29 in the second half by UCLA at Pauley Pavilion as the Wildcats drop their fifth game in a row to the Bruins.

In Arizona's season finale, the Wildcats lose 80-69 on the road to Oregon.

UA finishes the year 17-9 overall and 11-9 in Pac-12 play.

After the game, Miller said he was pleased with the team's overall finish despite not having postseason incentives to play for.

"I’ll just share with you what I said to our team after the game: This is the 17th team that I’ve had as a head coach, and I’ve never been prouder of a group of guys than I am of this year’s team," Miller said.

A week after Arizona's season ends, UA president Robert C. Robbins says he expects Miller back for the 2021-2022 season. 

"He’s out there recruiting," Robbins says of Miller. "I think signing day is coming up soon. We’ve got a really good team. They’re young, but good. And we’re eager to move forward and get the final chapter of this now-almost four-year saga over. But Coach Miller is our coach."

The University of Arizona announces it is parting ways with Miller after 12 years. 

President Robbins and athletic director Dave Heeke met with Miller this week and informed him of the decision.

"We feel like it's the appropriate time to make a change," Heeke said. "So that we can restore and begin to rebuild the overall high-caliber status of this world-class basketball program."

Miller ends his coaching career at Arizona with a 302-109 record (.735), three Pac-12 Tournament championships, five conference championships and no Final Four appearances.
