We've already dealt with them with Welker and Brady (knock on wood..........).
I hate to say it but I really think the Jets are the team to beat. Unless the Pats young guys on defense (Spikes, McCourty, Wilhite, Wheatley, McGowan, Meriweather, Brace, Guyton, etc, I'm looking directly at you) step up to another level, we're going to have a hard time stopping teams and we're going to have to rely on the offense again which hasn't worked so well the last few years. The biggest reason the loss of Warren hurts though, is his leadership and experience. The most experienced starter now on the defensive side of the ball is Wilfork (unless I'm missing something? Not counting Bodden, talking as a Patriot), which means A LOT of the leadership burden is going to be on Mayo and Meriweather, let's hope we'll be talking about those Mayo, Meriweather, and McCourty like we were of McGinest, Milloy, and Law.
