I agree that the pass blocking looks good. Our big guys are making walls. I am extremely impressed with Pettiti as he has far exceeded my expectations. He actually looks like a guy who has what it takes to be a starter in this league. I figured we would have lots of growing pains with him. But it looks like he is as good a RT as we have had for quite some time.
However, I am underwhelmed by Al Johnson. I have noticed him getting beat/pushed around numerous times, and I haven't even been watching him.
I agree our run blocking isn't doing too good, and I don't know why. If I had to guess, I would bet it is because we are doing too much scheming on run blocking with down blocks and pulling. I think that works good on the sweeps, at times, but in between the tackles, I think our big boys need to be just firing ahead and taking out what is there. When we do all the pulling in our between the tackles running game, Julius has to wait for the lineman, the plays become slow developers and generally lose efficacy. Straight ahead blocking with Julius hitting the hole at the speed of his choice (and not that of blockers) is what works best for our running game.
