Replicating what the defense is going to see on Saturday with Florida State's dual-threat QB in Tommy Castellanos isn't easy, and none of the QBs on the Crimson Tide's roster have a skill set that is similar to his. He's a naturally quick and shifty runner who won't be easy to contain.
Freshman QB Keelon Russell has some mobility, but he doesn't possess the speed Castellanos does.
Fortunately, Alabama has a former dual-threat high school QB who also happened to be one of the best athletes in his recruiting class and was willing to step into that role this week to simulate what the Tide is going to see with Castellanos operating a Gus Malzahn offense.
