As likable as Golden is, we won't even know if he's the real deal for another four or five years. Mid major guys sometimes workout fantastically (like aforementioned Meyer) but the common theme among the real successful major conference coaches seems to be a relatively high level of success at a lower-tier school in a major conference.
Guys I see making a big splash in the coming decade would be Dabo Swinney, Jim Leavitt, Jim Harbaugh should he ever come back to college ball, and Mark Dantonio, should he decide his health is good enough to carry him through, could go on to have very good success out of Michigan State like Saban before him.
