We do not have a dominant run game. We have an opportunistic run game. Williams is great, but his supporting cast is not constructed to maximize his yards if we run him all the time. He will do best if Book can complete the short passes. If Book cannot (or if Wimbush cannot), then Williams will have a harder time of it. That's not a knock on Williams. I love him as a running back, and I think he has a great future ahead of him. This Irish team is just not built to put him in front. Book needs to jab, jab, jab before the Williams roundhouse comes.
