A follow-up on Mike Nolan's hotly contested replay challenge against the Eagles in Week 6: His overall challenge record is 12-18 in three-plus seasons as a head coach, but the record is only 6-14 for home games. He lost two challenges during the 40-26 defeat at Candlestick Park.
These numbers are according to me. I have tracked replay reversal information by team, coach, referee and replay official for all games since 2003. I check the numbers against certain league totals each offseason.
By my count, the Cowboys' Wade Phillips is the only head coach with a winning reversal rate among coaches with at least 10 coach-initiated challenges since 2001. I've got Phillips at 8-3 since 2003 after he won two challenges Sunday (this includes 4-0 on the road).
Mike Shanahan is next at 25-26 (.490), followed by Jeff Fisher (13-14, .481), Marty Schottenheimer (12-14, .462), Mike McCarthy (6-7, .462), Dick Jauron (11-13, .458), Bill Parcells (10-13, .435), Scott Linehan (8-11, .421), Tom Coughlin (16-24, .400) and Nolan (12-18, .400).
Coaches have initiated more challenges at home. They have succeeded in a lower percentage of home challenges. Perhaps they take chances challenging calls at home because they feel more confident about winning those games.
Nolan isn't the only one with a particularly poor challenge record at home. I've got Romeo Crennel with an 0-13 challenge record at home, but 4-6 on the road. Gary Kubiak is 0-6 at home and 4-9 on the road. Jim Haslett is 1-11 at home, 3-6 on the road.
