LOL ... this has come up several times with people suspecting he will un-retire sometime during the season. This way his body would be in better shape for the play-offs.
The last week of pre-season Gronk is gonna unretire. He just doesn't want to have to go through camp again. You heard it here first.
I tend to agree with CF. I don't think you will see him week 1. But if the Patriots are 6-2 or better after 8, I could see him unretiring for the final push.
There is some chatter that there is a FA TE that the Patriots have an agreement and the signing will occur after May 3rd to avoid costing a comp pick.
