I think a lot of people on this board are missing the point. The Bills can only win a Super Bowl by having better players than other teams, especially the Patriots. I think it would be idiotic if the Bills selected a less talented player because it is a position of supposed greater need. It is hard to get quality defensive ends, especially in later rounds; however, the Bills have to have a play maker, and I really do not want to see them reach like they did with Whitner. If the Bills absolutely need to draft a wide receiver, they should trade down to get more picks.
As far as offense vs. defense, I am sure the Bills are going to go heavy on offense in this draft, but if a better player is available on defense, I think they have to select him. Both sides of the ball were really bad, hence the 7-9 record. It was a team effort.
