So when will the Dallas Cowboys announce who the new play-caller will be?Well, it wont be any time soon. But they wont wait until theyre on the bus on the way to the first game, either.So theres a pretty big window on that decision.What were trying to do right now is, were going to work through the mechanics of that here through the off-season, Cowboys coach Jason Garrett said Wednesday at Valley Ranch. I dont want to definitively say that one way or the other. Again, like I said, theres been a evolution here of me trying to delegate a lot of responsibilities I had as an offensive coordinator as I became the head coach. So were trying to move in that direction. Bill and I have talked about different ways that we can do it.The discussion is apparently going to take a while.Garrett was asked why not announce it now, before the OTAs and/or training camp.That very well could happen, he said. Probably not here today on Feb. 13. But as we go, we will work through it. We trust the process. We are confident we will get it right.-- Carlos MendezTwitter @calexmendezGo to our Cowboys Corner blog for more.
