This is pure speculation, as I don't know the kid, so no offense is intended if any relative, friend, etc., reads this...
But was this maybe an academic issue? I feel like we lost a recruit (or a transfer, or something) once before to Slippery Rock once before (and now that I think about it...maybe it was basketball???), and it was an academics thing.
Well, if Slippery Rock wasn't NCAA DII, I might jump on that theory, nut a non-qualifier is a non qualifier for NCAA, and any test score issue would have 3 more attempts to meet.
