I agree about the big back idea....A big back effects an opponent's secondary players in a lot of ways....Really big stud all the CBs will dread tackling him....Big back tires a defense and sometimes gets them to break....
However, I don't like the idea of Gator running the ball, at all, because we need him running routes and being a reliable option for Cato on 3rd down. We only have him and Shuler that we can trust to catch a critical pass.
Putting him at FB could get him injured and miss games. It's not like he isn't effective at TE and needs to be moved to get him involved.
You could always throw to him laterally or WR screen that's basically the same effect of a run play in space.
