You don't have to worry about it anymore, as he'll never be on our team again.
Also, as said before, I don't think it was just Locke. But he sprang to my mind. Your large market argument doesn't hold a lot of water to me. Around the league, Salt Lake is known as having the most opinionated/engaged fanbase. While the scrutiny is high on a national stage in markets like NY and LA, I think it is safe to say that the ferocity of judgement is just as severe, if not moreso, here.
Also, I'm not excusing Kanter. What he did was immature, wreckless, and will cost him fans and potentially dollars. It cost his team a win.
I just think there is some of the pregame that was taken out of context, and some of it could've been said to protect himself from the boos he thought he'd hear. Those who study psych know this behavior all too well. Some people who fear impending confrontation will sometimes create a confrontation. Also, he's immature, has a language barrier, and watches too much wrestling. But he's lying when he said the boos didn't bother him. He wants to be loved, and fearing he wouldn't get it, he created the opposite.
My theory.
****ing shame too. Some would have booed him, but most would've been fine with the trade request I feel. It was addition by subtraction with Rudy and Derrick.
