Well, its very very early in the process. There have been a lot of good points made in this thread. Here's my take: There are two good things for the Bills and their needs this year:
There are at least three, maybe four teams in front of us that are going to draft QBs—and we don't need one. Moreover, I'm not sure I'd draft anyone of them over EJ if he was there. That, of course, is highly debatable, but the bottom-line is, we're not in QB seeking mode, and at least four teams in front of us are. So that leaves us looking at the other five/six best options.
Building on the first observation: Not only are we now able to focus on the five best non-QB options, this is a draft deep in talent. Especially at one position we are in need of, an OT. Also, if Watkins for some odd reason does drop to 9 (I don't really see that happening—and, especially if Robinson is already off the board), then I see him as the pick. But, I doubt that scenario plays out, which means I think the Bills end up taking the unsexy, but very needed, best OT they like/want at that point, sans Robinson.
The only thing I know for sure: It's going to be a long three months!
