Have you guys not seen him play? He moves slowly and looks bored when he’s playing his ass off in the Stanley Cup Finals - that’s just how he is.
Putting Kuch in a skills competition and expecting flash and excitement was the equivalent of putting Larry Bird in a dunk contest* and then complaining that he’s not slamming like MJ while smiling like Magic. It doesn’t play to his strengths, it doesn’t showcase what makes him great, and that just isn’t his personality.
* Just so people don’t get the wrong idea, Bird absolutely could and did dunk. The guy was closer to 6’11” than the 6’9” he was listed as and in his younger, pre-back injury days he was far more athletic than people today give him credit for. But he was never flashy with his dunks like he was with his passes - he was much more utilitarian when it came to that aspect of his game, and he wouldn’t have been very fun to watch in a dunk contest.
