I very much disagree. K doesn't go after every call, in fact, he's pretty good at just choosing the ones that are REALLY bad. I see him sitting on the bench "smelling his finger" a lot during bad calls.
WRT the foul, I had a very good view of it in person, saw Singler do nothing at all to get that position, except box out like he should. My voice was ragged by that point in the game, but I SCREAMED about it nonetheless. Even the Wisconsin fan next to me didn't quite understand the call.
