Rob Gronkowski, TE
He's a rookie no more. And what's with that silly rookie title last year anyway? Gronkowski stormed the NFL scene with 42 catches for 546 yards and 10 touchdowns, the latter of which was a Patriots rookie record for a tight end. At 22, 6 feet 6 inches and 265 pounds, his blocking and pass-catching abilities make him an invaluable asset for years to come, stabilizing a position that until last year hadn't been much of a factor.
