Arizona football training camp notes and observations, practice 2: Receiver Isaiah Mizell shines in team periods

Here are notes and observations from the Wildcats’ first training camp session at Davis Sports Center and Dick Tomey Practice fields:

* Among the top performers on Thursday: second-year wide receiver Isaiah Mizell, who caught multiple passes from quarterback Noah Fifita and ran for extra yards in the first team period. Mizell had one of the top plays of the day with a deep touchdown catch from Fifita down the sideline. With Charlotte transfer cornerback Dwight Bootle in coverage, Mizell won the 50-50 battle and scored the touchdown. The Orlando native is considered one of the fastest players on the team and is “night-and-day different” compared to last season, according to offensive coordinator Seth Doege.

* The first set of defensive backs in Arizona’s first 7-on-7 period featured Wyoming transfer cornerback Tyrese Boss, Nebraska transfer Malcolm Hartzog, USC transfer Matai Tagoa’i, UConn transfer Lee Molette and Charlotte transfer Dwight Bootle. The first drive ended with Fifita throwing an 18-yard touchdown to wide receiver Giovanni Richardson.

* The second set of defensive backs in Arizona’s second 7-on-7 period were Swayde Griffin, cornerback-converted-safety Johno Price, Northern Colorado transfer Cam Chapa, Kingston Spivey and Howard transfer Zuri Watson. The period ended with second-year quarterback Luke Haugo throwing a touchdown pass to West Virginia transfer receiver Rodney Gallagher III.

* Arizona had multiple special teams periods, including field goal. Kicker Michael Salgado-Medina, who’s entering his second season as the starter, made several attempts, including a pair of 42-yard field goals. Freshman kicker Ian French made a 35-yard field goal. Punter Chase Ridley, a freshman from Perth, Australia, had multiple sky-high punts and recorded hang times — using our stopwatch — of 4.45, 4.65, 4.81 and 4.83 seconds.

* Backup quarterback Sawyer Anderson had multiple impressive passes in a team period, with completions to Colorado State transfer Jordan Ross, USC transfer DJ Jordan and third-year wide receiver Brandon Phelps, who dove for the ball down the right sideline with Spivey in coverage. Phelps’ catch is one of the front-runners for top plays of training camp thus far.

* Arizona is mixing and matching safeties throughout 7-on-7 and team periods. During team periods, two other safeties will stand in the back of the field and shadow pre-snap calls and alignment and mirror the safeties in the live action.

* NFL scouts from the Tennessee Titans, Indianapolis Colts, Atlanta Falcons and Carolina Panthers attended practice on Thursday.

* Former Arizona quarterback Jim Krohn and offensive lineman Glenn Parker were spotted at practice.
