This whole controversy is a logic professor's dream (I'm not one, by the way). ESPN is apparently reporting that it's the very absence of evidence that UF regards as a legitimate "cause." The underlying fallacy here is that it's impossible to prove any negative generalization. I can confidently assert that no dog can recite the Gettysburg Address, but I can never prove it because I don't have access to every dog, living or dead, and new ones are being born all the time. Similarly, the Gators can never prove that Mac never received a death threat(s) at any time. They could nail him on the charge only if he made a specific, verifiable claim that could be shown to be false.
