Given next years schedule I would suggest Stoops ride this out (as if we have a choice) - however if I were Barnhart, I'd already be sending out feelers to gauge interest in the long shot gets. Perhaps that is unethical but this is SEC football we're talking about.
This approach of trying to hire that lottery ticket coach - the untried, unproven coach who magically is the next Bear Bryant just isn't working - we don't have the program or the AD to pull that off, and I hope that UK fans don't let loose with the unmerited optimism should Barnhart yet again go in that direction.
