I've changed my mind. I originally wanted Rob Ryan. I would still be ok with him. But I've decided I want someone else:
The guy played WR at Stanford under Dennis Green and Bill Walsh.
His dad was a coach (in KC once).
He's been an Assistant Coach in the NFL for three teams.
He's coached under Jim Harbaugh.
He has a great track record of developing players, and would be perfect as a HC to develop a drafted franchise QB (he's been a QB coach).
To say his players are smart is a bit redundant as he coaches at Stanford.
Nonetheless, I think he'll be a helluva head coach in the NFL, and I'd love to see him in Kansas City. He looks good in red. (EDIT: And he just turned 40...perfect age/temperament)
