Shaka should definitely get at least one more year. Many of his recruits will finally be upperclassmen by then, and he'll have his best shot of any year he's been here.
Fans need to realize 2 major things:
1. UT is not a basketball school where lofty expectations are unquestionably in order, and finding the "right coach" is all that's needed to suddenly change everything. You guys think who the coach is matters way more than it actually does.
2. Shaka's entire performance all the years he's been here have been seen through the lens of the strongest conference in basketball. You could take the exact same Texas teams he's had and put them in C-USA and they would win conference titles. They'd get invites to the NCAA tournament because of it, and they'd get bounced early, but by and large the optics of it all would be decent and there would be much less fan unrest.
