BB easily has to go down a top 5 coach of the Super Bowl era.
Lombardi
Landry
Walsh
Parcells
I'm sure somebody could argue for a bunch of other coaches too. BB has three rings as HC and a great winning percentage. He's one more great season away from being the top HC of the era. If they went 19-0 he'd have it.
The only thing that I don't like about BB is the fact he hasn't yet really produced a successful disciple.

Charlie Weis, University of Kansas

Feels like most people BB produced weren't that good. McDaniels dismantled the Broncos. Mangini was run out of NY. Saban ran out on Miami. BB coaching tree is more like a pricker bush. Seems to produces lots of pricks.
