"Sources: Colts coach Tony Dungy is stepping down"

He’s had an absolutely awesome run as head coach, winning the Super Bowl (and giving the more reactionary the vapors with his postgame speech) and reviving two moribund franchises, interspersed with gutwrenching personal trauma–and steps down at the relatively young age of 53. Sounds like a wise move, if true.

Update: Dungy makes it official.
