Gronk won't stay healthy long enough to become the best ever. Plus, it will be very difficult to surpass Tony Gonzalez and Shannon Sharpe. Both stayed healthy through their careers and TB12 doesn't have much longer. If I'm not mistaken, this is only the 2nd time Gronk played a full season. And for the record, as much as I think AH is a murderous thug, he was better than 95% of the TE's in the NFL. He was a different TE than Gronk and could have played WR, H-Back and returned kicks. AH was a freakish athlete and with New England's history of "not paying their players" it shows how much Kraft and Belichick thought of AH to give him a $40 million contract after signing Gronk to a huge deal.
