"I just really want to be prepared for what we’re going for, what we’ve got planned for this year. Kyle Williams coming back was a big thing for me, so I want to the best I can for him and my teammates," he said. "I just want to come in in shape ready to go, but from there it’s just continuing to work hard, continuing to do what I need to do to fall into that role and just be the best person and player I can possibly be for my teammates."

Dareus and Williams have been teammates for the past six seasons. Entering his 12th year, Williams is the longest-tenured player on the Bills' roster. After that, it's center Eric Wood, who is going into his ninth season, and Dareus in his seventh.

"I haven’t been in too many seasons without him," Dareus said of Williams. "I mean, we’ve doing pretty well together, we have a lot of fun out there. I would say that he would be my work wife and we have good communication, so – we don’t fight, we don’t argue, we just kind of go with the flow."

Like with everyone else along the defensive line, the Bills are banking on a return to a 4-3 scheme benefiting Dareus.

"If everybody knows what they’re doing, there’s no problem with any game plan we’re going to be doing," he said. "So, whatever game plan we’re in, we’re just going to do the best we could and just focus in on know exactly knowing what we’re doing and knowing how to do it. With this defense, McDermott, he did a great job with that. He teaches me, he clarifies every position for everybody. So, do your job and everything else takes care of itself."
