Cowboys head coach Jason Garrett said Thursday afternoon he can see himself giving up the offensive play calling duties in the future, but it won't happen in 2012. During a news conference to introduce new secondary coach Jerome Henderson and offensive line coach/offensive coordinator Bill Callahan, Garrett said the head coaching position changes from year-to-year. "Absolutely, absolutely," Garrett said when asked if he will one day give up play calling. "I think you just get to a point where, 'Hey, I'm going to turn that over to somebody else,' and you've seen that around the league at different times and that's just part of the process that we'll go through."
