A closer look at Super Bowl referee

NEW ORLEANS -- Jerome Boger is the referee assigned to work Super Bowl XLVII.

Don't yawn just yet.

The NFL's handling of the assignment, while already under unprecedented scrutiny, will become a much bigger story if an officiating miscue influences the outcome between the San Francisco 49ers and Baltimore Ravens on Sunday.

Boger's assignment to the game has generated controversy amid accusations the NFL reversed eight negative marks from his report card.

The implication, spelled out by the officiating website footballzebras.com, is that the NFL went out of its way to assign Boger to the game in the interests of promoting racial diversity. The NFL has denied this happened.

Footballzebras.com has taken officiating coverage to new levels in a short period of time. We're left wondering to what degree the Boger report reflects legitimate concerns or sour grapes from anonymously quoted officials feeling jilted over their own standing within the officiating hierarchy.

Whatever the case, Boger finds himself under unusual pregame scrutiny through no fault of his own. He worked the 49ers' divisional-round victory over Green Bay without incident. He previously worked three other divisional-round games. He has never worked a conference championship game or Super Bowl.

As we noted back in October, Boger's crews have called a league-high number of holding penalties against interior defensive linemen. That was notable at the time because New York Giants offensive coordinator Kevin Gilbride had recently suggested 49ers defensive lineman Justin Smith "gets away with murder" by holding opponents to free up outside linebacker Aldon Smith for sacks.

Boger's crew has called a league-high 18 holding penalties against defensive linemen since 2008. That is about triple the average and six more than runner-up Ed Hocholi's crew. Boger's crew called zero such penalties this season, however. Crew tendencies can be difficult to discern because officals work a relatively small number of games. Also, regular-season trends might not hold up because the NFL shifts to all-star crews for the playoffs.

The first chart shows where Boger's crew has ranked in number of penalties called over the past three seasons. The NFL has maintained 17 crews. I've singled out a few choice penalties for display in the chart. The row showing personal fouls reflects calls labeled as unsportsmanlike conduct, unnecessary roughness and general personal fouls. Other 15-yard penalties are not included.

Boger's crew members called many of the penalties listed in the chart, of course. Referees are primarily responsible for roughing-the-passer and some holding calls. The NFL spells out each official's responsibilities on its website.
