If you see sacks as a real problem, then JP won't have much of a deep passing game. I'm not so sure about this with the new line. However, I do expect a much improved running game which, in turn, will produce a decent passing game.
We needed Willis so badly last year but the line was not up to par; the same holds true for the upcoming season. We won't win many games unless McGahee has a huge year for us. Moreover, I think Evans and Price will have their catches but their success will depend on the hands of the other receivers and our TE's as well.
I'm pumped and see at least 8 wins this year.
