I have no problem with what he's done thus far. If it ever crosses the line into something illegal or dangerous, that's a different story, but he's young and going to have fun.
The sad part to me, is that if he only has a good season this year instead of a great one, people will point the blame at this crap, rather than acknowledge that he's coming back from an injury and it's almost impossible to duplicate what he did last year (especially with more weapons in the offense this year). No, it will be all, "Gronk needs to refocus on football, it's no longer his priority, blah blah blah."
