Since you'll be reading scouting reports on every possible aspect of the upcoming Conference Championship games, we thought it would be enlightening to add the FO perspective on another aspect - the officials for both games. Football Outsiders keeps a database with every penalty called per season, but the important thing to note when reading this article is that playoff officials don't work with the crews that are assigned to them through the regular season - the postseason games get all-star crews. This means, of course, that tendencies may be different, and we don't have the names of each crew member, just the head officials. But those head officials have a lot of impact on what gets called.

New Orleans at Chicago: Terry McAulay

McAulay, an NFL official since 1998, started his career as a side judge and was promoted to his current position of referee (crew chief) in 2001. He has officiated one Super Bowl - XXXIX on February 6, 2005, when the Patriots beat the Eagles, 24-21. This will be his third Conference Championship game. In 2006, McAulay called the second-most penalties (239) for the fourth-most yards (1,655). His 6.924 yards per penalty was 13th in the NFL.

The Bears were the NFL's fifth-most penalized team in 2006, with 133 for 923 yards. The Saints were Chicago's mirror image - with only 90 penalties for 597 yards, they finished fifth from the bottom in total penalties called.

Both teams were in the middle of the pack in false starts (the NFL's most commonly called penalty this season by far) - Chicago with 22 and the Saints with 23. Where the teams differed was in the second most common infraction, offensive holding. Chicago was called 23 times for holding, while New Orleans had only 16 holds. The Bears had 13 more defensive offsides calls than the Saints (18-5), though New Orleans had twice as many defensive pass interference penalties (4-2). It's also worth noting Chicago's nine unnecessary roughness calls, three times more than New Orleans'.

Which team should be concerned with McAulay's penalty tendencies? The Bears know him better, as McAulay called two of their games this season - the Week 4 beatdown of the Seahawks, and the Week 16 squeaker over the Lions. Both contests were pretty evenly called, but very busy from a flag perspective. The 37-6 domination over the Seahawks saw 17 total penalties - eight for Chicago (the home team, as they will be here), and nine for the visitors from the Northwest. The 26-21 win over the Lions at Ford Field had 27 total called penalties and only 12 for the visitor. He called no Saints games in 2006.

McAulay calls a lot of penalties, but he doesn't have any grievous diversions from the norm. Both teams will want to be in their best behavior, but unlike out next contestant, there aren't any numbers that take you aback.

New England at Indianapolis: Bill Carollo

One thing that we've noticed at Football Outsiders in the four years we've tracked penalties is the amazing deviation from crew to crew when it comes to certain calls. In 2006, no referee personified that better than Bill Carollo. A side judge since 1989, he was promoted to the position of referee in 1996. Carollo has participated in two Super Bowls, and this will be his sixth conference championship.

Now, as to his most interesting number - Carollo called the fourth-fewest penalties (186) for the fourth-fewest yards (1,273), and his 6.8 yards per penalty average was - you guessed it - fourth. While he called his fair share of false starts (43), he almost never called offensive holding. Larry Nemmers and Ed Hochuli tied for the most holds called in 2006 with 42, and the league average was 33.5 per crew. How many did Carollo's crew call? A stunning 11 - all season - and three were against the New York Giants in Week 2.

Carollo called no Patriots games in 2006, but he did preside over the Week 12 45-21 Indy win over the Eagles at the RCA Dome. In that game, he called a total of four penalties, all against the home team. Certainly, he's as hands-off as McAulay is proactive.

Who benefits from this? The Patriots were called for ten more holds than the Colts (21-11). What about the illegal contact that the Colts will no doubt be conscious of? Carollo called that 10 times, tied with Gene Steratore's crew for second-most in the NFL. New England's been called for seven of those infamous infractions, with Indy having only three. But Carollo called defensive pass interference only five times, lowest of any referee. Most refs who call DPI a lot don't call much illegal contact, and vice versa, because the rules separating the two are confusing.

The Colts had 23 false starts in 2006, five more than New England, while Indianapolis was flagged for more than twice as many defensive offsides calls - 11-5. In this game, it's possible that New England can counter the Colts' tendency to fly off the line at (or near) the snap with a few extracurricular bear hugs.

Two crews with very different ways of calling their games will send their head men to preside over all-star officiating teams in the AFC and NFC Championship games this Sunday. So while you're watching Reggie Bush try to solve Brian Urlacher, or perhaps the conclusion of Peyton Manning's exhaustive battle with his ultimate postseason nemesis, remember that those guys wearing the neutral stripes can be decisive difference-makers.
