An offensive guard and both OT spots will need to be addressed. As is CB and FS.
Hopefully, the team allow Ellis Hobbs to walk. I'm convinced that even if Brady remained healthy, this team would never win another championship as long as Hobbs is starting. Yes, he's that bad.
Obtaining a high draft pick is preferable to attaining a vain playoff run. Cassel is simply too INT prone to make a real SB run.
BTW, to those die hard Pats fans that disagree with this thread, the reality is that the 2008 season is over. We won't win a SB with Cassel at QB. The sooner you all accept this the better off you'll be.
