I'm not sure the discipline would be fixed, because if it was going on under White's watch as a coordinator, it would continue as a head coach.
While he may have done the little things well, McDaniel ran the show on defense from what I saw. Now of course I've never been in a staff meeting with the Oakland coaches, so I don't know if White ran the show behind closed doors, but it's Gary Rankin's defense. McDaniel brought that defense with him to Oakland. The times I've watched him coach, whether it be at 7v7 camps, scrimmages, practices, or games, he's focused in on the defense. He lets the Offensive coordinator run the show on offense (which I believe screwed Tommy because went to the shotgun after going 12-1 the year before in the I form) and seems more like a manager.
This hire could set Oakland back for years if they get it wrong. Agreed?
