To expand on what I THINK Taylor was trying to say, is essentially this-
I don't think it had anything at all to do with fundamentals or teamwork. I really hope GL wasn't suggesting black people don't do those things and I don't believe she was.
I think the larger point was that in a system like Wisconsin you just aren't allowed to use your athleticism much. You don't have to be super athletic to make a pass, set a pick, and then cut. Every player wants to go somewhere that maximizes their skills and if one of your skills is athleticism, Wisconsin isn't going to maximize it. Sam Dekker is a perfect example. No one until the tourney realized he was athletic until now because Wisconsin's system doesn't intentionally try to display his athleticism. Sure he uses it occasionally, but were he at UK he'd be displaying it every single possession. Not better, not worse necessarily. Just different.
The larger, interesting thing to me is exactly what the article states. Wisconsin's non-Caucasian roster make up is far below the league wide statistic, and probably below the general population statistic. There is a reason that they had zero black players graduate the last 4 years, primarily because they have none.
While you can't draw any concrete conclusions, you can certainly wonder things. Either it's the athlete thing, but then you have to assume the proportion of athletic to non-athletic black players is not equal to the proportion of athletic to non-athletic white players. Which is certainly possible. Also possible the culture, city, life, etc. in Madison isn't appealing to a lot of black players (however, their football team seems to do okay at attracting black athletes) and it is also possible Wisconsin makes certain recruiting decisions based on race and perceived character, much like Coach K and Duke are often accused of doing.
No matter the reason, it is at least interesting that a basketball team manages to field a roster completely opposite of the sports general racial make up every single year.
