It's widely known that college basketball coaches - even Duke's Mike Krzyzewski - swear with relative frequency. But you don't usually see them dropping f-bombs live on television.
Coach K, who is the coach of Team USA, got caught cursing at his former player, Kyrie Irving, twice live on NBA TV. Irving joked about the way Krzyzewski waltzed into the lane during a demonstration. Coach K gave it back to him. It was obviously all in good fun.
