Just for s***s and giggles ...
But my first choice would be Mike Singletary. If you watched that guy during Senior Bowl week, you know how that guy coaches. Heck, just watching him get after it in drills, doing them full speed to show the players, then how he pumps them up would make me want to suit up for him.
But realistically, our problem isn't the HC, as much as it is our DC. And I will be the first to throw out a name(s) for that position -- Mike Pettine and Dat Nguyen.
Pettine is a young fiery coach from the Ravens. You may remember him from a TV show on ESPN called 'The Season' that documented him and his father coaching HS football in Pennsylvania. Mike has since went on to coach at various positions for the Baltimore Ravens, and is currently their OLB coach. If you remember him from this show, you remember that he was a take no BS kinda coach. But at the same time, he got his players ready and motivated.
Dat Nguyen would be a reach, but I love that guy. Probably one of the most cerebral players in recent memory. He wasn't the biggest, strongest or even fastest, he just studied film and understood the game better than anyone. I can remember so many times him yelling out plays before the snap, because he studied film that much. He played the game with so much passion it was unbelievable, and he does have Big 12 ties. He is currently a quality control and assistant LB's coach for the Cowboys.
