How long is a ball of string?

No one really knows. QB doesn't influence running game. Match tactics do.

i think he's talking about the QB runing the ball on his own. like how important is it that the QB scrambles in this game.
The answer to that would be: not at all. it's not important whatsoever.
The QB's sometimes rush the ball, but noone really knows why. maybe it's because they see that nobody's opne, mybe it's because they see a good running lane? no idea.
i always had the QB i have now, and he often ran in the lower divisions, and hardly ever does so now. that's my experiance.
it's not really a factor though.

Your passing would suffer, but your running game wouldnt be affected at all

allright, thanks, guys!
