How often does a coach get fired and immediately get another HC job for the next season? That rarely happens. Harbaugh will do it since he has a Super Bowl but McDaniel? I don't think he's getting a head coaching job and I sure as hell don't think he's gonna trick another (old ass) owner with that no energy, charisma-less gimmick. Owners are looking for leaders of men right now.
He should become an OC, put up crazy numbers and then try again when we get back to owners chasing after offensive geniuses whether they're leaders or not. If I was him I'd go to either Philly or Detroit.
