I don't think the Rockets laughing at him blowing a wide open dunk is really that far out of bounds as far as acceptable play. It would be different if the Rockets went and started throwing out in interviews and saying stuff to him about it. But in the moment that seems completely normal. I don't think it is a matter of bad sportsmanship or anything. It happened in the game and was funny, especially given Curry's 'Golden-boy' treatment by the media. It happened the players laughed as they should, and now they can focus on what they need to do to win the next game. Let's take care of business. As far as the fans go we should absolutely use it every chance we can. We should let Curry and the Warriors remember that for a long time.
