I'd rather have Lawrence Frank. Sorry, but Mike Brown came off to me as a bit "clownish" and I think he'd be wise to take some rest and get away from the game for a year.
I also believe that this hiring is important because this person could be the "coach in waiting." Not a certainty, but I believe that this hire will have that thought on the backburner. With that said, I would NEVER want Mike Brown as a head coach...
