Verbal commit, Justin Taylor.
Alabama is still a bit shallow in the running back department, believe it or not. The team has only three scholarship running backs. Here are some other players who may get some carries come game time.
Blake Sims, Sophomore, 6'1", 210 lbs.
Blake was an outstanding dual-threat high school quarterback, but his size limited the amount of schools that wanted him throwing the ball. He's going into his redshirt sophomore year, and after two years the coaches have yet to decide on a permanent position.
He looks to remain as a contributor at running back, and that may become his permanent position, but I see the coaches doing something else with him. If safety Robert Lester leaves early for the NFL (and there's not much reason why he shouldn't, he's a top-5 safety on many draft boards, top-3 on some) then the Tide will look a little thin in the defensive backfield.
A very interesting fact is that when Alabama was preparing to play LSU they did not use Sims to play the role of LSU's scrambling quarterback, Jordan Jefferson, during practice, despite the fact that Sims truly can run and throw (much better than Jefferson, I'd wager!). They used redshirting receiver Duron Carter.
Brent Calloway, Freshman, 6'1", 210 lbs
Calloway wants to be a running back, and that's why he switched his commitment to Auburn for a short period before recommitting to the Tide, but he's best-suited to play linebacker, and Nick Saban made that clear.
His run-in with the law over a marijuana incident may indicate he doesn't have the discipline required of a Saban linebacker, as they must study film relentlessly whereas the running backs do not.
Saban is brutal when it comes to discipline, and Calloway's future at the Capstone is still uncertain. Until further notice he is still in Saban's doghouse.
If he can correct his mistakes and play to his potential (which could easily involve the NFL) he will become one of Alabama's next great linebackers, and won't touch a football unless it's an interception or fumble recovery.
Nick Tinker, Junior, 5'10", 207 lbs
Tinker is a walk-on running back. He has the size yet lacks playing time. Running back isn't a position you learn; you either have "it" or you don't.
Ben Howell, Senior, 5'9", 202 lbs
Like Tinker, Howell is a walk-on. He's spent his career on the scout team. Though he hasn't helped the team during game time, his contributions on the scout team are certainly appreciated.
Justin Taylor, Freshman, 5'10", 205 lbs
Taylor is the final running back on the Tide's roster, but he's only a verbal commitment, and hasn't (and cannot) officially sign with the Tide just yet. He is the lone running back in the 2012 class.
Rivals lists him as a 3-star prospect, as does Scout.com. The stars he's rated by may prove to be silly, as Alabama recently had a 3-star prospect running back named Mark Ingram.
The odds of another dark horse like Ingram coming along are slim, but if anyone can make it happen it's the Tide's running back coach, Burton Burns.
