After our football team (which was ranked 6th nationally in D2) took a pasting in Kansas over the weekend, I got a note about this article by some researchers at the Univ. of Arkansas that suggests D1 basketball programs that are more successful lead to lower graduation rates. ParaPundit thinks this would lead astute administrators to kill off their basketball programs, but I'd note that this isn't true for D3 programs according to this article, and it doesn't even appear true for football.
