To me it sounds kind of like a chicken or the egg thing...Stubby leaves the TE end to block and the TE gets destroyed and the running game stalls. Maybe if the TE is a guard or tackle the running game doesn't stall, again, especially on your own 1 yard line.
I'm not trying to be argumentative, just trying to make sense out of Stubby's decision to keep a TE in to block who obviously can't block. And if that TE is never targeted, or if he is and he can't make the play, then the whole idea of Richard Rogers being in the game is insane compared to an extra guard or tackle.
