Agree with OP. When you have a big guy like McCullers you have to use him. Play your defense, dont change who plays for them, maybe just the scheme. He could have been causing problems all night for their QB. Just not smart coaching IMO. As far as Croom goes, we do need some guys to step up even it is Freshman. Who cares what year as long as they are talented and can play.
NOW, the RB position. Marlin Lane should be playing hands down. He can run more aggresive and make people miss much better than Neal. He fumbled in the Florida game I think and didn't get much time since. Neal has fumbled also, as long as Lane doesn't show a habbit of it he should be the guy IMO.
