ORCHARD PARK, N.Y. -- Richie Incognito didn't show up to the Buffalo Bills facility with bandoleers lashed across his chest. He didn't roll a hand grenade into the defensive huddle. He didn't jump into an SUV and do donuts on the practice field.

Incognito was polite and reflective on his first day with the Bills, who claimed him off waivers from the St. Louis Rams on Wednesday.

Incognito has a reputation for being one of the NFL's dirtiest players. He has committed 11 personal fouls since 2006, the last two coming Sunday. The Rams were fed up. They ejected him from the team.

Bills linebacker Kawika Mitchell, a team captain, blasted the Bills' decision to bring Incognito aboard. Mitchell, who is on injured reserve after season-ending knee surgery, tweeted:

"BIGGEST DISAPPOINTMENT THIS YR. THE GUYS A BUM. DIRTY AND ALWAYS WILL BE. REALLY WISH I WAS PLAYIN RITE NOW. SERIOUSLY... I KNO WE'RE N NEED OF OLINE BUT THIS GUY ..."

Mitchell finished his thought with an obscenity.

Incognito was aware of Mitchell's comments.

"I did see them," Incognito said. "I haven't spoken with Kawika yet. Like you said, I have a reputation around the league for being a less-than-model citizen and some guys on teams really dislike playing against me.

"I can see where Kawika's coming from. I've probably done some cheap stuff to him, playing in the past. But now, the onus is on we're a team now. We're members of the same team, and we're working toward the same goal, and that's getting this club as many wins as possible.

"So I think it will all transition. I knew something like that would pop up. It's not a big deal."

Incognito's contract is up after the season, so his Buffalo career might last only three games. If there is a new collective bargaining agreement, he would be an unrestricted free agent. If not, then he will be restricted.

He suggested a change of scenery might be enough to change perspective.

"I'm going to continue playing my game, playing the way I play," Incognito said. "I'm going to be a lot less selfish with the penalties and just the acting out. I think I was just so frustrated with putting in so much hard work and pounding the details and then just coming up loss after loss after loss after loss after loss.

"I mean, the last three years we won five games total. That's a lot to lose, and it takes its toll on you as an athlete more than I really imagined. And now it's good to take a step back, get out of the situation and come here with a clean slate and play ball."
