A lot of coaches like him are jerks, it’s part of what makes them successful. He’s always been this way, but 2 titles just puts a bigger microscope on him. It also gives him more confidence and arrogance to act like a bigger jerk because of his success.
Half wsy agree with ya. His over the top competitiveness is what makes him successful, but being a jerk about it… is clearly a character flaw. And when things don’t go right - things quickly fall apart and the players will begin to doubt and turn on him. It’s a known fact that when things are good - all is well, but when things go bad and in times of adversity that’s when you see someone’s true character!
Sure the two championships SHOULD give him plenty of confidence, but not arrogance. If anything it should only make him more confident, comfortable and able to take the criticism, and just smile and bite his tongue at the arrogant fans that show little class… rather then lower yourself to there level. It’s a very immature response, and actually shows his insecurities snd lack of confidence.
