An end-of-season look at where NFL officiating crews rank in a few categories where discretion and controversy tend to apply, listed by referee (with Walt Coleman scheduled to work Seattle's wild-card game Sunday):
2010 Defensive Pass Interference by Crew
The second chart breaks down defensive pass-interference numbers by crew for the last three seasons.
2008-2010 Defensive Pass Interference by Crew
The next chart breaks down offensive pass interference by crew for the 2010 season only.
Note that Coleman's crew has called only one such penalty this season, second-fewest in the league behind Seattle favorite Bill Leavy.
2010 Offensive Pass Interference by Crew
The next chart breaks down the offensive pass-interference calls by crew for the last three seasons.
2008-2010 Offensive Pass Interference by Crew
The final chart shows three-year totals for roughing the passer, by crew.
Seattle fans might remember the controversial roughing penalty against Seahawks defensive end Raheem Brock during the team's defeat at New Orleans in Week 11.
The pivotal play did not draw a fine, tacit admission that referee Mike Carey's crew erred on the call.
Coleman's crews have only four roughing calls over the last three seasons, fewest in the league among referees working continuously since 2008.
