You can't overstate the importance Jamaal Williams is to the run game. I believe that if he had played yesterday he would have had several big runs and probably at least 1 breakaway run. There were some gaps and seams that Lasike, Brown and Hine just couldn't hit like Williams can. These other backs are good players, Jamaal is a great player.
The O-line will get better every game. They are young, but talented and hungry.
