Disagree. Good sportsmanship says you call off the dogs down 11 with only ~20 seconds to go or whatever. But what was Dillon supposed to do? Just hold the ball and turn it over on a shot clock violation? No. He was perfectly within his rights to shoot it, and sportsmanlike to make sure it was a low percentage shot instead of doing something like driving to the basket.
Agreed. If there was no potential shot clock violation and he had done that, I would agree with K that he was kind of showing off. But he hoisted up a 35 foot jump shot just to beat the clock. I don't think he Dillon even thought it was going to go in.
K should worry about talking to his own players about the repeated bush league shit they do. That guy has no shame.
