Absolutely TE is 3rd to 5th round.
Also I am not sure the Bills need that Nelson - Cook - hybrid type TE/WR Field stretching TE with Owens and Evans on board next season.
Remember there is just one Ball. Our TE needs to catch 35- 40 passes a season. Move the chains, hold on to the ball, run after the catch and Block his butt off.
I like Gronkowski in the 4th or 5th round not just because his is local. I heard the SEC safety from Oregon on Sirus say Gronkowski was the best TE he faced. Big strong and Fast. His combine numbers outstanding, He is more athletic and faster than Pettigrew AND He really wants to play here.
