The season is all but over for the Buffalo Bills as they've been eliminated from playoff contention with two games remaining. Sunday's loss to the Washington Redskins solidified that, and also led to a great deal of controversy and frustration between the coaching staff and players.

Mario Williams, for one, doesn't believe the coaching staff has held players accountable enough given the defense's struggles this season. He also voiced his opinion on needing to take a pay cut to remain in Buffalo next year, putting that idea to rest.

Following Williams' comments about scheme and accountability, defensive back Corey Graham called him out and essentially told him to do his job and do what he's asked.

Here's what he said, via Matthew Fairburn of Syracuse.com:

It's tough. Obviously he's got his opinion and everything. In this league, when things aren't going your way, everybody's negative. That's how it is. I'm used to it. I'm not going to sit here and say one person's right and one person's wrong. Rex is proven in this league. He's been doing this a long time. One thing I can say about Rex, he's a smart guy. Very, very bright guy. He knows defense. He know what to do, what not to do. You just have to find your place, find your place in this scheme and find out what you need to do. When these guys are defensive linemen, they want to rush. We're not going to sugarcoat it, he wants to rush the quarterback. When you ask him to do something he's not comfortable doing, it's tough for him. But as a professional as a defensive guy, you just have to go out there, do your job, do what they ask you to do and do it to the best of your ability. Don't worry about things like that. We have to win as a defense and as a team. We have to do whatever it takes to win. If it means dropping back in coverage, you have to do it sometimes.

Graham wasn't attacking Williams, but more so telling him to focus on the game and not the coaches. Williams has recorded just four sacks, so he's clearly someone who can afford to improve his numbers given his expensive contract. He's an important part of the Bills' pass rush and defense and in order to get pressure on the quarterback, he needs to make that happen off the left side.

With two games remaining, the Bills have to come together and play as a team -- something they haven't done on defense lately. With "drastic changes" supposedly coming from Ryan, these final games will be important for several players -- Williams included.
