Haven't heard a sniff of it down here in GA. By all reports he's very content in Athens, and any rumblings from the Bulldog Nation were quieted by the great way that they finished out their year.
Mid-season there was a little rumor going around that he might be interested in the Miami job (he's an alumnus) if it were to come open, but then when it actually DID come open his name never came up at all. So I think Richt will be there for awhile.
