Brad was obviously very defensive in the post-game interview. He has to know a lot of the issues with this team are very much his fault, and yet he can't admit it to himself or anyone else. (Issues other than Tomi's mono, KJ's arm injury, or the appalling bad officiating at MSU.)
For example, regarding a question about our guards' lazy, casual, too-cool-for-school turnovers, Brad appeared to (intentionally?) misunderstand: "I write it down on the board before every game! We can't have 17 turnovers!" (Translation: It's their fault, not mine!) But the question was clearly not about how many turnovers, but rather about how come we have so many bad (unforced) turnovers. I think that's when Brad cheap-shotted Piper: Brad was acting-out from a feeling of defensiveness, and tried to shutdown Piper (who was too nice to go after Brad with a pointed follow-up question).
