Who will call Cowboys plays in '13?

We still don't know whether Dallas Cowboys coach Jason Garrett will give up his play-calling duties in 2013. If he is forced let someone else make the game-day calls, who might take over that role? ESPNDallas.com's Calvin Watkins opines:

"Offensive line coach/offensive coordinator Bill Callahan? Quarterbacks coach Wade Wilson?

Is looking outside the organization an option? Hue Jackson, who interviewed for the offensive coordinators position with the Carolina Panthers this week, is somebody worth mentioning. Tony Sparano, the former offensive coordinator with the New York Jets, could be given another tour of Valley Ranch. Pete Carmichael Jr., is a free agent, after working as the New Orleans Saints' offensive coordinator this season. What about him? Jim Caldwell has done a solid job since taking over as Baltimore's play-caller. Caldwell interviewed for the Cowboys' head coaching gig that eventually went to Wade Phillips in 2007.

If Garrett loses his responsibilities, the smart money is to make Callahan taking over."

If Jerry Jones takes that job away from Garrett, Watkins thinks there is a legitimate concern about how that could affect Garrett's leadership in the locker room:

"[D]oes Jones have Garrett's back? By taking the play-calling duties away from him, do the players think that Garrett is on a short leash because of a potential move?"

There is no doubt that Jones has all people in the Cowboys franchise walking on egg shells right now. Time will tell whether that approach will pay dividends next season.
