i think thats a risk gain kind of offense. Look at it this way even though they may be bigger and stronger they will also be slower. I know the argument now is that guys are getting faster and bigger, but in all reality these defensive line man run 4.5 40s now. thats insane! so they will be alot faster than the offense and if an offensive guard or fullback take a bad angle, whoa those linebackers will be flyin past them and blowing up the play. But u got the other may. the bully, the mash, they gain yards. Risk and Gain.
