I hate watching 4th and short. We come up short way to often. I would think that there are certain cases where we could line up somebody special in the fullback position and let them block. TE - possible, but the position is thin and usually in these situations we have two TE in the game already. OL - possible, but these guys are kind of slow and we want to hit the hole fast. DL - possible. LB - ideal. Think about it. In Tressleball it is another "Big Speed" position. You invert their role and let them shoot the gaps for the offense. I wouldn't want expect a LB to pass block, run routes or god forgive take a handoff but I can't think of another person on the team I would who's lead block I would rather follow. I would take our LB's, with a head of steam, to blow away any opponents LB that might be loitering in the hole. I know Katzenmoyer did this a couple of time and there was all sorts of hoopla about 45 being in the backfield again. Just a thought for LB's having a situational role as FB.
