I can understand your historical point of view, but let me say what the fuck does it matter. If Smart's results are essentially equal to the last years of Barnes then he deserves to get fired. And it doesn't matter what Texas fans deserve. If the current coach isn't passing muster then you get another one and that's the way it is at any school.
I don't know which coach Texas could reasonably get and it's a crap shoot on getting the right one, but I'd want one that would kick Dylan's ass for loafing last night. Of all the problems with this team, effort should be the easiest one to fix. I've criticized Osetkowski and Roach for not having much basketball IQ, but when that is combined with lack of effort by your team leaders (seniors), then that reveals a toxic atmosphere and it is time for the coach to go. Again, who gives a fuck what the fans deserve or think. This is a decision to be made by the AD.
