The problem in Dallas is not who will be calling the plays. It's the undermining and the idiocy of Jerry. If he didn't want Garrett to lead this team, he should have canned him and hired BC. If he would have done that, there would be no lame debate about who is calling the plays and no wondering aloud what Jason's role with the team is now.
The fact that Bill is participating in the undermining of the head coach tells us more about the guy's character. And his pandering to the fans with how flattered he is to become the Cowboys' player caller rings as hollow as ever.
Bill should have said that he would be glad to take over the plays so long as the head coach supports the decision. The fact that there has been no official announcement and no confirmation of the decision by Garrett means, at least in my mind, that he was never consulted about this change to begin with.
Maybe Bill can be successful. But it sure isn't getting off to a very credible start.
