Just watching Playbook on NFLN and saw that Gronk is 85 yards from tying Dallas Clark for most yards by a tight end in one post-season. Not necessarily a lock to break it (ankle, game plan), but a possibility. Just imagine if he had Eric Alexander covering him for one whole game.
Gronk will be the key. If he can't make cuts or be effective in pass game, then Pats will need to quickly adjust and keeping him as a decoy to block maybe the best option. Of course this puts pressure on AH and WW. I expect the Giants secondary to cheat up since we really have no WR speed threat
