If anything, I would expect to see just the opposite - but probably both will return. Parcells is NOT going to call it quits just when we're hitting our stride. He built this team, and I don't see him walking away from it when we're on the verge of being a true contender for several years to come. And I don't think Jerry will want to reliquish his cash cow TO, who sells tickets and jerseys and draws media attention. Both will be back, bank on it.
I am more worried about Glenn - who is our deep threat if he comes up gimpy??? Crayton, Witten, Hurd are possession guys, we need a fresh face in the same mold as Glenn, IMO. But we won't be taking a WR until the 3rd rd earliest. First we need to improve our pass rush abilities (think LB), OL (we're an injury away from mediocrity again), and a FS/nickle CB/KR would be nice.
