Maybe, but again, I don't think you're factoring how hard it is to win in bball at Clemson. Relatively speaking, it's a small school, in the middle of nowhere, contending with Duke, UNC, etc... in the ACC, that only cares about football... and secondarily about baseball. I'm not saying a great coach couldn't have gone there and done better, but they have as little resources and support for bball as can be had at the P5 level. If I had to pick a B10 equivalent, I'd say MN, with 40% of the enrollment. And, I guarantee you MN spends a greater % of their athletic budget on bball than does Clemson.
Getting IU level results at Clemson is pretty good. Exceeding them is really good, and that's what he's done. What he could do with IU resources is likely exponentially better. I'm not saying I want Brownell, I'm just saying he's way, WAY better than CMW.
