Okay, a couple dilemmas.
The first, naming a starting quarterback.
The second? Stacking a depth chart with six -- if healthy -- capable tailbacks.
Entering fall camp senior Silas Redd and freshman Justin Davis were the frontrunners to land the No. 1 and No. 2 spot, redshirt sophomore Tre Madden also listed as a co-starter, but seemingly on the outside looking in.
Redd has been sidelined as he continues to rehabilitate a knee injury suffered during spring practices. Davis has been on the sideline with an undisclosed injury. Madden in the meantime has been taking all their carries, all while wearing a yellow no-contact jersey.
Redshirt junior D.J. Morgan has also been sidelined during fall camp due to injury. He was buried on the depth chart out of spring.
Freshman five-star recruit Ty Isaac has also caught the injury bug and spends the days watching from the sideline.
Which means redshirt sophomore Buck Allen, once an afterthought, has emerged and looks to be in shape to challenge for a significant role. Allen was buried on the depth chart out of spring, listed fifth behind Morgan.
Four player injuries later, Allen is now getting an opportunity to shine.
"For a guy who really has never played here before, had been buried on the depth chart before and I think we've talked about it a number of times, "Kiffin said, "sometimes when change happens… guys get new chances, clean slates. I think Buck has really taken advantage of that on and off the field."
Allen knows with so much depth at the position, this is his chance. On day ten he took a handoff from quarterback Max Wittek, broke a tackle by outside linebacker Devon Kennard and ran about 50 yards for the end zone.
The 6-foot-1 215-pound back told FOX Sports NEXT he's doing everything he possibly can with the extra reps. "[It's] just giving me an opportunity, giving me a chance to show what I can do," Allen said. "It's giving Coach Kiffin a chance to believe in me, trust me with the ball."
Allen, now emerging on the football field, has also started to emerge in the classroom. When talking about the redshirt sophomore, Kiffin brought up how well he did last semester.
"I improved on [school] over the years," Allen explained. "When I first got here I wasn't that good. I'm very happy with myself with that in the classroom. It's something I focused on. Coach Kiffin told me ‘Whatever you do in the classroom is going to carry over to the field, and I think that's what happened. I performed in the classroom real well and it carried over onto the field."
Though Allen has been showing an ability to break tackles and run for the end zone, plenty of time remains in fall camp for the other backs to get healthy and challenge again for the starting spots.
"We were at practice 11 yesterday," Kiffin explained, "and I looked at it and a guy can improve twice as much, get to practice 22 and it's still a day before preseason game three."
In other words, though Allen has done well through twelve practices, there's still plenty of time for him to get knocked off by another back.
"I think I put myself in a great position [to get playing time]," Allen said. "We are going to push each other and make each other better. When one goes down we're going to pick each other up. Me and Tre are pushing each other and the guys on the sideline are pushing us."
