Jerry Jones said the Dallas Cowboys haven't discussed having offensive line coach Bill Callahan take over play-calling duties for head coach Jason Garrett.

“I believe in a head coach being one of the coordinators,” Jones said. “That’s debatable. I’ve had people say the head coach needs to be what I call a walk-around head coach, and that is he just looks at everything. We’ve had at least two of them in Bill Parcells and Tom Landry — of course I wasn’t here when Tom was here — that did everything. They ran the whole thing. Although they had coordinators or run coaches or passing coaches. I’m sounding a way that I don’t want to sound because it can work.

“I like the coach being one of the coordinators, preferably the offensive coordinator. But of course in Wade Phillips’ case, he was the defensive coordinator. When you do that, you’re going to get in down times, loss times. You’re going to get people to say, ‘They do too much. They’ve just got too much on their plate.’ You have to look at that. Jason has huge capacity to cover a lot of ground, so if anybody can do it, or look to the future, he can.”
