Flipping the appearance of misconduct on the person that observes the misconduct is some real mob-lawyer logic. I am surprised you didn't write "it would be a shame if something happened to you" in that post. In my experience, there is a strong correlation between how indignant someone gets at an accusation and the likelihood they did something wrong.
A lot of the decisions by Mitchell and Joplin in particular were weird in that game, and not consistent at all with their previous performance. Talk to anyone that follows betting, and there are many of these examples popping up. The only place "innocent until proven guilty" happens is in a court room. Otherwise, reputations are earned, not given, and none of us have an obligation to assume anyone is innocent. When it linked itself to gambling sites, sports took the risk that the integrity of the games would be questioned. So I am questioning the integrity of the Marquette/NC State game, which is absolutely my right to do.
