Everyday the Patriots are knocking off their needs. Their defense could end up being elite if they are able to keep Wilfork or replace him with more of a penetrating dt type like Aaron Donald. If they could bring in a top level safety that would help as well.
On offense, I don't think we can count on Gronkowski to stay healthy at this point. This team will only be successful offensively if they can maintain the run game, when Brady has to drop back 45 times and throw to Edelman, Amendola (when healthy), LaFell, Dobson and Vereen it could be a struggle. Would love to see them draft an impact receiver or tight end, then again with a strong defense, scoring points at a really high rate becomes less necessary.
