I am not saying TE is set.....but I'm not saying a QB is regressing when he has a bad game either, as you say.
The TE's were not a factor in that game, very true. But there are several things that may go into that.....need for more blocking as the line was poor, they may have been open, but watching on a TV you can't see it and he just did not throw in the progression, just a few possibilities.
IMO it's knee jerk reaction after a game to make a broad statement. Do we have a Gronk type? No we don't and that's maybe because they are not out there to just pick off a TE tree.
IMO we have bigger issues to deal with as Whit may well retire, if Suh, Peters, Fowler, Barron, CJ, Talib may retire...that's a lot of D players who may be leaving....some will be taken care of in house with in house younger guys, but I think those are more prominant in us keeping the ball going forward than getting a TE like Gronk.
