Jerry Jones said any decisions regarding the Dallas Cowboys' offensive play-calling system will be made by coach Jason Garrett -- and not by the owner himself.

At last week's Senior Bowl workouts, Jones strongly hinted Garrett would not call the offensive plays and that the duties likely would be given to new offensive coordinator/offensive line coach Bill Callahan.

And in an interview posted Thursday on the team's website, Jones again hinted that there would be a new play-caller.

"Jason is putting together, as he should be, a staff and a philosophy on every phase of the team ... (relative to helping) us win a football game, now and in the future," Jones said during the interview. "Now being '13 ... I'm excited. We got a good man in Jason Garrett putting that together for us."

Jones acknowledged being defensive about the perception of his head coach's power and expressed confidence in Garrett's decision-making process.

"I'm on the defensive, I guess I am, sitting here defensively about (the perception)," Jones said. "But it is just not, in any way, the way that it is.

"Let me say this, I must say this: (Calling plays as head coach) has never been an issue with Jason Garrett. Never. That was his GM, that was me … by having him come in here as play-caller and doing that for the very first time."
