Miami Dolphins pass rusher Mario Williams and the Buffalo Bills did not have most amicable breakup after a contentious 2015 season.

Williams grew frustrated with his role in Rex Ryan’s defense, in which he was deployed as a 3-4 outside linebacker rather than his traditional role of a 4-3 defensive end. The veteran pass rusher publicly questioned Buffalo’s strategy, claiming that dropping him into coverage was a waste of his talent.

Williams was accused of quitting on the Bills late in the season (the film suggests he did put forward his best effort) and he was cut this offseason before signing with the Dolphins.

Ryan, who isn’t afraid to broach any subject, went off on Williams during an interview with the MMQB’s Jenny Vrentas:

“Mario Williams, yeah, but he is making $17 million dollars [in Miami]. Guess what, it wasn’t going to happen. Now look, with some of the comments [he made], do I wish him well? Not really. But, he’s on Miami. If he would have gone somewhere else, maybe. He’s a good kid, but I am used to some mean motherf—ers that play out there. The Terrell Suggs, Jarrett Johnsons of the world. I screwed them, too; I had them drop [into coverage], too. Not one of them bitched. Von Miller [dropped into coverage] in the Super Bowl. Why? Because that’s what’s asked of him; that’s what his job is. Your job is to play. Coaches spend a hell of a lot more time studying tape and everything else. They are trying to put the team in the best position to be successful, not an individual.”

It’s hard to argue against Ryan here. Williams could have kept his complaints in-house, played through the season as the Bills fought for a playoff spot, then moved on in the offseason.

The entire interview, which includes Rex’s brother Rob, is worth your time.
