I think "hostility" is an exaggeration. More a "frustration" with those who think we need to have Calvin Johnson and Des Bryant clones in order to be competitive. While I would love to have that, reality dictates its unlikely to happen.
Clearly we have vastly different viewpoints about the state of our receiver corps. "Trainwreck" is NOT how I see it. But that's OK, I'm not trying to change your mind.
I, along with BB (by inference, don't believe in the value of WR's to the ultimate impact on the Pats won/loss record. And aside from the question of durability, our current WRs have just as much raw talent as Givens, Branch, and Brown had. The issue of staying on the field is a legitimate one, but no one can predict injuries.
Personally, I won't be irate if we pick a WR with one of the first 2 picks, but I just don't see it happening. As to Margus Hunt, I think at 59, he'd be worth the risk. His athletic ability is clearly elite. I think its worth the chance that he'll develop the technique and instincts that would allow his rare talent flower, but I understand that he could just as easily be a one trick pony, who will never develop past a guy who can do only one thing well. I just think at the end of the 2nd round the reward would be worth the risk.
I think the discussion of whether you need elite receivers to win, or can you do it with just competent ones and a great QB is a fascinating topic that will fill our time until the real games start. For example if I could only have 5 truly "elite" players on my roster, none of them would be a WR. Of the top of my head, QB, LT, DL, S, CB. would be my choices But that's me.
