I don't think OBJ's time with the Giants was contentious, whatever his preferences. He routinely seemed to be fine there when interviewed. Who knows what's going on in his head, but OBJ was always a loud personality. Nobody ever wondered what was on his mind when he was in college. He wasn't a problem, but he wasn't a quiet guy who blended in either.
What's up with Eli Apple? Dude roasted the Giants and Saints, then insulted the fans, and then went a step further to trash the city of New Orleans and then say the food is horrible. Now he's trolled the Chiefs players, offering them tickets to the SB. All I really know about him was watching him with the Saints and the playoff games with the Bengals. Nobody should be a douche, but when you're not even good enough to earn some passes, you really should try harder to do the bare minimum. And by "bare minimum" I mean....you know....not insulting and picking fights with fans and insulting their cities.
Guys who quarrel with their peers within the league or management may have some growing up to do. When you can't stop yourself from blasting the fans who make your career possible, you have major character flaws.
ETA: And if you dis NOLA's food, then you've left "douche" and crossed into "dumb" territory.
