IRVING, Texas -- With the NFL's game of musical chairs involving head coaches just about over -- except for the uber-patient Cleveland Browns -- let's look at the effect the new names in new spots will have on the Dallas Cowboys.
In 2013, the Cowboys went 1-4 against teams with new coaches. The lone win was the October meeting against Chip Kelly's Philadelphia Eagles, but they returned the favor in the more-important Week 17 rematch that won the NFC East.
The Cowboys also lost to Kansas City's Andy Reid, San Diego's Mike McCoy and Chicago's Marc Trestman.
Gruden and O'Brien will be head coaches for the first time in the NFL. Whisenhunt had a six-year run with the Arizona Cardinals.
The Cowboys went 0-3 against Whisenhunt. Two of the losses came in overtime and the third was by a point. And they were three of the strangest losses. In 2008, they lost on a blocked punt for a touchdown in overtime. In 2010 they lost in part because David Buehler missed an extra point. In 2011 they lost in overtime in a game in which many believe Jason Garrett iced Dan Bailey at the end of regulation.
(Personal aside: I don't believe that was the case. The play clock was running down and Garrett called the timeout at the request of special-teams coaches Joe DeCamillis and Chris Boniol. Bailey's first miss of that season at San Francisco came with the operation rushed because of the play clock. Now back to your regularly scheduled programming.)
O'Brien was the New England Patriots' offensive coordinator in 2011 when Tom Brady beat the Cowboys on a final-minute touchdown pass 20-16. The Texans have the top pick in the draft and a team that could be in line for a quick turnaround.
Gruden was the Cincinnati Bengals' offensive coordinator when Bailey won the game on a last-second field goal after Andy Dalton was limited to 206 yards passing. The Redskins folded under Mike Shanahan and have a ton of needs, but the return of a healthy and motivated Robert Griffin III could change their fortunes quickly.
The Cowboys could have six more games against teams that will lose assistant coaches in 2014.
As of Thursday, the only assistant the Cowboys have lost is Boniol, who oversaw one of the best kickers in the NFL. Maybe that will change too. Maybe.
