Allen, a redshirt sophomore, and Mitchell, a redshirt senior, have had to adjust to a new system for the first time in their Razorback careers with the implementation of a new coaching staff, headed by Bret Bielema.
Offensive coordinator Jim Chaney has worked with successful quarterbacks at the collegiate level from NFL veteran Drew Brees to NFL quarterback-to-be Tyler Bray, but his Arkansas signal callers are still trying to learn aspects of his and Bielema's offensive playbook.
"Anytime you learn a new offense, you've really got to get into the playbook and study it as much as you can, just to get as familiar as possible for when you go out there and practice it," Allen said. "It's always tough learning a new offense, but it's not something I struggle with. Going out there and practicing every day is definitely making it easier."
Mitchell, who Bielema said referred to the old terminology at times prior to spring break, agreed with Allen in that simply working with the new playbook is making the transition go more smoothly.
"The first two days were rough because we had some of the same words that mean totally different, opposite things," Mitchell said. "So the first couple days were rough, but now it's easy. We've gotten in the playbook and studying it. Even over spring break, it was something we really focused on."
Even though experience under previous coaches like Bobby Petrino, his brother Paul Petrino and Garrick McGee does not necessarily give Allen or Mitchell an advantage in learning a new playbook, Allen said his experience last year was vital to his maturation as a quarterback.
"I think if anything it was just the fact that I got out on the field and got my feet wet," Allen said. "Especially the Alabama game, SEC play and things of that nature. Just to say it's not going to be brand new to me when I get out there; being out there on the field and getting snaps were huge for me."
Although coaches have mentioned lefty Taylor Reed, Brian Buehner and walk-on A.J. Derby in the quarterback competition, Bielema and Chaney both recognized Allen and Mitchell as the signal callers getting most of the first-team reps. Mitchell, who spent most of his time at wide receiver last year, said he knew what was in store for him when he moved back under center.
"Every practice I was with the QBs up until team and things like that and (pass skeleton)," he said. "It's been a transition a little bit getting back used to throwing the ball all the time, walking around with coach Chaney and getting used to the new verbage and things like that.
"I knew what I was doing last year. I knew what was going to happen this year and it was clearly explained to me that if I wanted to play receiver the next year, I would have to prove myself again at quarterback. So I knew what I was stepping into and it was something I happily accepted.
"Competition makes everybody better. That's something I had to go through competing with Tyler. It's the same thing we're doing right now with me and (Allen)."
