According to Fox, Gronkowski’s shenanigans are over.
"There is little doubt after spending just one day at New England's training camp that the Summer of Gronk has ceded to the business of Patriots football. The foolishness is over. There will be no more dancing shirtless in clubs, at least not until the season is over. Fun is fun, and business is business. In Bill Belichick's world, the two do not mesh. Ever."
Gronkowski is a character. The Patriots cannot change that. But on the field, Gronkowski also is the best tight end in the NFL. As long as Gronk isn't getting into legal trouble, it's worth the tradeoff.
