Jason Garrett might give up play-calling duties to Bill Callahan. Then, again, maybe he won't. Both Garrett and Callahan spoke to the media this week, but it remains a mystery about who will actually call the plays for the Cowboys in 2013. Cowboys tight end Jason Witten said it's not about who calls the plays, but how they are executed. The Cowboys were sixth in total offense last season, but they were only 15th in scoring.
