Might have some rust as a rookie (didn't play football in 2009)
Summary: Gronkowski is a very well-rounded tight end prospect and will likely come off the board in the second round, but if team doctors have very serious concerns with his back (and some certainly should) then he could really fall in the 2010 NFL Draft. Back issues are probably the worst kind of injury for an athlete and generally these athletes have injury problems throughout their careers. Gronkowski will never be an elite tight end in the NFL, but if he stays healthy he should certainly be a productive contributor and starter.
Player Comparison: Kevin Boss. Boss and Gronkowski have similar frames, athleticism and receiving skills.
