Memphis fans actually should be raked across the coals for running him off. He was performing to the level of their program, maybe even a bit above.
For some reason, they think they're a real basketball school just because the city loves hoops, but historically, they aren't a great program.
Tubby was plenty good enough for Memphis, especially with as corrupt and political as that city is and how they tie the hands of everyone who tries to coach or succeed there.
If they'd actually let the guy coach instead of forcing him to babysit the Lawsons or staying home because the team isn't competing for a title, they might have had a little success. But with the way they're running things, it'll take a guy like Cal to make them relevant, and a guy like Cal isn't taking that job unless it's someone who gets fired for the FBI stuff.
