If UA can land Ivan Rabb, that might cement the No. 1 recruiting class in 2015.

No surprise but…. with the addition of guard Allonzo Trier last weekend, Arizona’s 2015 recruiting class ballooned up to No. 1 overall so far in the updated team rankings from 247 Sports.

The recruiting-oriented website has UA on top of its own rankings, which are based on evaluations by analysts Jerry Meyer, and on top of its composite rankings, which incorporate a rankings from other websites.

Meyer says the rankings are based on both quantity and quality in a complex algorithm that a “monster army” of staffers work on.

Scout.com also has Arizona and Duke in its top two at the moment but has not released team rankings yet, according to analyst Josh Gershon.

Arizona has landed three five-star players so far: Trier, guard Justin Simon and wing Ray Smith.

Of course, there’s still a long way to go to determine the final 2015 rankings, but if UA can round out the class with a highly rated big man such as Ivan Rabb or Chance Comanche, look out.

Arizona “could have the best recruiting class in the country if it got Allonzo Trier, Ray Smith and Justin Simon and one or two other guys,” said Clark Francis of Hoop Scoop. “If they get Ivan Rabb that’s a top one, two or three recruiting class.”

While Comanche and Stephen Zimmerman have planned official visits to Arizona, Rabb’s situation is still unknown. He’s in Dubai right now, where USA Basketball’s U17 team just beat Greece, though Rabb did not play because of an ankle injury. (The full U17 schedule is here).

Trier was initially invited to the Elite 24 showcase game on Aug. 23 but has pulled out (the latest roster is here).

Trier's mother, Marcie, told the Star via text message that he decided not to play because his little sister's birthday is that weekend and because he will leave for Findlay Prep the next weekend.

"It was a hard decision to make, but Zo will leave for prep school for a year then straight to Arizona the day after school ends and will be gone a long time," Marcie Trier said. "So we want to cherish these last few days with him."

The Washington Post took a long look at Trier's complicated course through high school, after he left Maryland's Montrose Christian to play for Findlay next season.

With Trier aboard, the chances of Isaiah Briscoe choosing UA appear remote but he's been keeping the possibility open while nursing an apparently broken foot he hurt in the Fab 48 event at Las Vegas last month.

UA guard Jacob Hazzard and the rest of the Pac-12's exhibition team are gathering in the Bay area today before heading to China on Sunday to begin their tour.

Former UA target Bennie Boatwright has committed to USC.

ASU landed three-star wing Dominic Green.
