Referee confidential: Upon further review

Posted by ESPN.com's Mike Sando

NFL referees suffered a season-high 11 replay reversals in Week 14, including the first of the season for John Parry.

In an upset, the replay officials working with referees Jerome Boger and Bill Carollo did something neither had done all season: issue a replay challenge in the final 2 minutes of a half.

Replay officials have initiated 67 challenges this season, but only two combined against Boger, Carollo, Mike Carey and Carl Cheffers. Four other referees account for 39 of those 67 booth-initiated challenges: Ron Winter (11), Gene Steratore (10), Tony Corrente (10) and Ed Hochuli (8).

Seahawks coach Mike Holmgren lobbied in vain for a replay challenge after Cheffers' crew ruled the Patriots' Jabar Gaffney down by contact before fumbling in the second quarter Sunday. The replay official for that game -- retired referee Larry Nemmers -- has not challenged Cheffers all season.

Replay officials produced 26 reversals in 256 games last season. They have produced 26 reversals in 208 games this season. The number of booth-initiated challenges is about the same (76 last season, on pace for 82 this season). However, as noted previously, replay officials challenge referees at inconsistent rates.

The chart ranks all 17 referees by most replay reversals of any kind (coach- and booth-initiated).

Within the division: Former Rams coach Scott Linehan leads 2008 NFC West coaches with a 1-0 record in replay challenges. His successor, Jim Haslett, is next at 2-1, followed by the Cardinals' Ken Whisenhunt (2-3), the 49ers' Mike Singletary (1-2), Holmgren (1-3) and former 49ers coach Mike Nolan (0-4). League-wide, coaches have a 69-116 record (.373).
