Not to mention that most special teams coaches are used to getting the most out of the talent at hand, since they're typically working with backups, so I would hope he'd be looking for the same perspective in OC/DC. Certainly would beat a total tear down to implement yet another system.
The thing I can't get past with McDaniel, though, is the whole Tebow fiasco. That, to me, took some serious bad judgment, the very type of bad judgment that you would try to avoid in your head coach.
