Calls and Effect: AFC East penalty tracker

For a considerable chunk of the season, the Buffalo Bills led the NFL in penalties.

They surrendered their status as the least-disciplined team in Week 9 only because they had a bye. When the Bills fired head coach Dick Jauron after Week 10, opponents had accepted 80 penalties, one behind the league-leading Green Bay Packers.

Amazing, then, what the Bills have done in their four weeks under interim coach Perry Fewell.

The Bills have become one of the best-behaved teams and have fallen way down the list to 13th.

The Bills committed 11 penalties in Jauron's final game. Since he was fired and Fewell was promoted, they've elicited six, three, one and three yellow flags.

Of course, Wednesday's addition of St. Louis Rams guard Richie Incognito off the waiver wire might shoot that trend all to hell over the last three games.

Incognito likely will start on the right side against the New England Patriots on Sunday in Ralph Wilson Stadium. The Bills on Friday placed Kendall Simmons on injured reserve.

Incognito is volatile. He has been flagged seven times for 75 yards. He has been cited for unnecessary roughness three times and a personal foul. The Rams waived him because he committed a pair of 15-yarders and got into a heated confrontation with head coach Steve Spagnuolo last Sunday.
