Seriously? Davante Adams refused to play another game for the Packers. Now Deebo is demanding a trade from the 49ers. Wilson demanded a trade from the Seahawks. Arians said he was lied to and "refired" from the Steelers. Those are just off the top of my head, and those are all teams with "winning cultures".
Then there's OBJ's comments on the Browns, years of players badmouthing the Bengals (until this year), Watson demanding a trade from the Texans (before his legal issues), and pretty much everyone (understandable) blasting the Jaguars.
Then there are players who have their own issues, such as Antonio Brown pooping on the Steelers, Raiders, & Buccaneers, Michael Thomas' issues with the Saints, etc.
I'm sure we could go on and on, and without much effort find bad things players have said about just about every team except the Patriots & the Super Bowl champs.
