Defensive end Mario Williams’ 2015 season with the Bills was marked by his complaints about what the team was asking him to do on defense and complaints from others that Williams wasn’t giving the team everything he had.

That unhappy mix and Williams’ big cap number led the Bills to part ways with Williams once the season came to an end. Williams landed with the Dolphins as a free agent and he’s singing a different tune when it comes to fitting into a defense than he was last season.

“At the end of the day, whatever scheme that defensive coordinators have or whatnot, you have to take it and adjust to it and run with it,” Williams said, via ESPN.com. “It could be anything. It varies not just [for] myself, but my teammates. They’ve been other places and experienced other things.”

The reason behind Williams’ change of heart isn’t difficult to figure out. The Dolphins want Williams to rush the passer first and foremost, which eliminates his biggest bone of contention from last year.

“I think the biggest focal point and exciting for us is knowing that [we can] cut it loose,” Williams said. “It’s almost like saying, ‘Go! Every time, just go. We’re going to put you in the best position for you to get after it and everything else is going to trickle downhill from there.'”

It’s not the first time we’ve heard this kind of positivity from Williams about his role since he joined the Dolphins. That probably won’t make for many smiles in Buffalo, but it could be the foundation for a rebound from Williams in Miami.
