I for one would love a guy at RB who specializes at scoring TDs.

I hear you. Marcus Allen for example, not a real big back, no doubt was one of the greatest short-yardage backs ever. But I also think there's a correlation between a back with size/strength and his ability to run inside the tackles where the traffic is relatively heavy, especially where the defense stacks a lot of bodies up at the los in short-yardage scenarios.
But whoever said bringing in LT is an Ahman Green redux got it right.
