The rundown: The heart and soul of Arizonaβs defense is a trio in the secondary: Stukes, Johnson and Smith.
Theyβre the only scholarship defensive backs at Arizona with at least two seasons under their belts at the UA, and theyβre the Wildcatsβ most experienced with a combined 11 seasons β nine from Stukes and Johnson.
Stukes, Johnson and Smith have combined for 431 tackles, eight interceptions, eight forced fumbles and 29 pass deflections in a combined 4,550 defensive snaps. Stukes said, βWe take our roles as leaders seriously and be role models any way we can, just trying to make sure everyone is on the same page and holding everyone accountable.β
Entering last season, Stukes was called college footballβs βbest-kept secretβ by former UA defensive coordinator and defensive backs guru Duane Akina, but Stukesβ would-be final season at Arizona was cut short due to a season-ending knee injury. Stukes medically redshirted and returned to the Wildcats for his last hurrah as a college player.

Stukes, Johnson and Smith briefly entered the transfer portal in December, but opted to return for another season at Arizona.
βThey believe in what weβre doing because they had a bunch of people try to get them to escape Tucson and they wouldnβt leave,β said Arizona defensive coordinator Danny Gonzales. βThey believe in what weβre doing.β
Stukes said he didnβt enter the transfer portal βlooking for a place to go.β
βI was just kind of protecting myself in a way, just so that I wouldnβt be trapped here, trapped somewhere else if, heaven forbid, something went wrong,β Stukes added. βI was in constant communication with all my guys. We were all talking about whatβs going on, what we were thinking.
βI was talking to (head coach Brent Brennan) and Coach G the entire time and they did a great job just re-recruiting. They just reset it, laid out what they got planned. I trust them.β
Stukes, who has experience at nickel back and cornerback, wasnβt the only devastating injury in Arizonaβs secondary last season. The Wildcats also lost Maldonado, a multi-year starter whoβs now at Kansas State, to a season-ending knee injury. Arizonaβs injury-riddled defense was mostly depleted in the secondary after playing 13 defensive backs last season.

Even Davis, who transferred to Washington, was impacted by injuries throughout the season despite playing in 11 games.
The injuries thrust other defensive backs into more prominent roles; βthe race to maturity,β as Brennan called it. Like Smith, who started at three different positions in Arizonaβs secondary last season and had the third-most tackles (63) for the Wildcats, along with six pass breakups, two forced fumbles and a fumble recovery. Smith earned Co-Big 12 Defensive Player of the Week honors following Arizonaβs win over Houston.
βOnce Gunner Maldonado went down, it meant Genesis had to step up,β Johnson said. βI think he did a great job at that. Now, after getting that experience, one thing I noticed in spring ball was his voice and his energy. If I had a bad day mentally, Gen was the one lifting me up and vice versa. Heβs young, but I can count on him as a vet.β
The 6-2, 202-pound Smith βhas grown as a player and as a man,β Stukes said.
βI think thatβll be evident,β Stukes said. βThe game is going to slow down for him. If you havenβt heard of the name yet, you will this year.β
Defensive back Genesis Smith eyes the ball while running footwork drills at the University of Arizona footballβs Spring Showcase in Tucson on April 19, 2025.
In the spring, Smith was among the top playmakers on defense for the Wildcats and consistently produced interceptions and tackles near or behind the line of scrimmage. Smith βcould be the best defensive football player in the league this year if he does the things he did in spring ball,β Gonzales said.
Johnson (strong safety), Stukes (nickel back) and Smith (free safety) are the seasoned veterans that headline Arizonaβs secondary, however, the Wildcats have other players who benefitted from injuries and earned playing time, like Groves-Killebrew, who started six games for the Wildcats last season after transferring from Louisville. Luttrell, a Tennessee transfer, played nearly 400 defensive snaps and tied Smith for a team-high three interceptions last season.
βWe have a lot of ballhawks, dudes making plays on the ball each and every play in the spring,β Smith said. βWe just gotta continue to pursue the ball and be physical.β
Still, the Wildcats needed to bolster their secondary after losing two starters (Davis and Maldonado) and several other depth pieces, after having the 12th-best passing defense in the Big 12 β and the 14th-most interceptions. Arizona added nine defensive backs in the offseason, including four from the portal β who are all expected to have significant roles.
The aforementioned transfers have played a combined 4,630 defensive snaps in their college careers, according to Pro Football Focus.
Cole, who previously played for Brennan and Viney at San Jose State before his lone season at Texas, could conceivably start at cornerback opposite of Groves-Killebrew. Cole, who Viney called βSteady Eddie,β was consistently a starter during team periods in the spring.
βHeβs a young man that shows up every day and is always ready to work,β Viney said. βJayβVion has grown tremendously not just physically, but the mental capacity and football IQ part of the game. Heβs a young man that weβre really pleased with thus far.β
Stukes, Johnson and Smith are bona fide starters, but determining other spots in the secondary will be decided in training camp and the days leading up to the season.
The Wildcats could also turn to their five freshmen at defensive back. Four of those defensive backs hail from Texas; Hinton, the son of former UA defensive back David Hinton, was an early enrollee in the spring after a standout career at Chandler Hamilton.

Gonzales said, βWith all of the injuries we went through last year, we werenβt deep enough on either side of the ball.β
βThose guys that came in (last season), they gained some experience, but they were obviously not good enough to compete at a high level in the Big 12,β said Arizonaβs defensive coordinator. βThe Big 12, from top to bottom, is a very competitive league. If you can stay healthy, you have a chance to make a run like those guys up north (Arizona State) did.
βWe addressed that issue and weβre significantly deeper across the board. ... Iβm really excited about what we did in the portal on our side of the ball. Weβve got a little bit more depth than we had last year. We need a little bit of luck to stay healthy, which every good football team has, and thatβs the direction weβre headed.β
Gonzales is known to have an aggressive style of defense from his days as a defensive play-caller at Arizona State and San Diego State. The Gonzales-led defense will have some new elements this season, whether itβs disguised blitzes or a 3-3-5 scheme.
βCoach G is a super smart guy,β Stukes said. βHeβs got a couple of different things that weβre going to work in this year. Weβll have some similar stuff from last year, but as far as how our style is going to look, he puts people in positions to showcase their ability and make the most out of their talent. ...
βAs long as everyone is on the same page and playing at a high level, weβre going to have the chance to be pretty good.β
