The single smartest nugget of basketball knowledge I ever heard was from Hubie Brown, who taught that screens are set for one reason -- to make defenders think. It’s pure genius.

I’m not saying this is as good as what he said -- only that’s it the cleanest and best advice I can offer on any one subject.
