re: Is Les Miles or Mark Richt the "Mac Brown" of the SEC?

I don't think either of them compare to Brown. Brown has gotten lazy and has no sense of direction with the program.

Miles and Richt are the same coaches they have always been, I don't think either of them are working less or changed philosophically

Expectations, Richt made it to Atlanta for the last two years and beat UF this year. Was a few seconds away from going to Miami. I think he at least met expectations the last two years if not exceeded.
Miles coached the best team in LSU history just last season. Didn't meet expectations this year but not like he went 3-9. SEC is tough, couple of bad bounces and you finish third instead of playing in Miami.
