Jason Garrett talked for more than 26 minutes Wednesday without taking a question or, as far as anyone could tell, a breath. Then he fielded questions for about 26 minutes more, exhausting the gathered media in the process, but never conceding that he has lost the play-calling duties to Bill Callahan.

And maybe, he hasn’t. Maybe at the end of these long off-season deliberations as to how offensive plays will be dispatched to Tony Romo in 2013, Garrett will remain the play-caller.

That seems highly unlikely at this point. Garrett would have been unlikely to put such a happy face on his willingness to delegate the role down the line to Callahan if he were going to emerge from an off-season of change at Valley Ranch as the offensive play-caller.

But there’s one thing the Cowboys’ head coach is right about. When I asked if he feels we make too much of how the plays are called, Garrett said yes. And if it’s a simple transference of duties from Garrett to Callahan while both, along with other offensive coaches, are designing game plans, I wouldn’t look for drastic changes in how the Dallas offense looks and operates this fall.

“Bill wouldn’t be on this staff if we didn’t have shared values,” Garrett said.

Besides, think about this for a second. On a number of plays — an increasingly larger number each season, it seems — Romo goes to the line of scrimmage with options as to which play to run based on the look of the defense.

In that sense, it is more of the “collective” process that Garrett talks about than we give it credit for being.

Garrett insisted that the final decision on who calls plays will be his. But having spoken enough in the past about his desire to be the play-caller, the closest Garrett came to conceding that this may be a Jerry Jones decision was this explanation for why a change could be made.
