No one is saying you hope to get stuffed - you hope for a good block and one broken tackle for 10+ yds. But if it only gets 2-3, it's still setting up multiple looks and spreading the defense E/W you live with it. I thought this game - they ran the play the right amount of times, IMO.
You're still looking at it wrong. Lots of teams run up the gut and gain 1yd and then again for 4 and then again for 3 - all to setup the play action pass. The more effective the run the more effective the play action. Now, think of that same play as the bubble screen. You fake wide and hand off up the middle (where our RB's had a filed day against Maryland) or you run the QB away from the screen side (where Hunt ran for tons) or you have your WR fake the bubble and double move (why a lot of guys were open, even if Hunt doesn't see them).
