almost every decent playoff caliber team in this league has a 1A receiver. The Bills need that. It would make Trent better and it would make a Schouman/Fine TE combo better. They need to procure one of the top FA WR's this year.
In addition, a C is needed who can contribute within the next two years, and have upside for beyond that time. I really like the dude from Alabama.
We need a good pass rushing DE, either top flite from the draft, or if not, FA.
I believe if its the right personnel, this team can make Jauron look very good.
