Excerpts from the scouting reports on Gronk coming out of college:
Hands: Shows great concentration and hands while going over the middle. Nicely snatches the ball outside his frame, much more so than other top tight ends Jermaine Gresham and Aaron Heranandez.
STRENGTHS
Gronkowski has prototypical size and good speed. Shows fluid hips and runs precise routes. Possesses the lateral quickness and burst to get open in man coverage. Catches the ball away from his chest and displays good body control. Effective blocker that can generate a push. Very productive in his two seasons in the Pac-10.
Not a whole lot there about how you better have a super accurate QB if you expect Gronk to catch any balls.
Actually, I was surprised at the number of reports that didn't have as much more than an adequate starting TE even IF his health held up. Particular amusing was the frequent 'can't make people miss after he catches the ball'. Yeah, no. He doesn't need to make anyone miss.
It takes 5 or 6 of them to bring him down.
