Australian point guard Matthew Dellavedova plays defense like a UFC fighter crowds an opponent, minus the punching and kicking. He gets in your face, gets under your skin, gets into your head.

When the Aussies played Serbia in an Olympic preliminary round game earlier this week, Dellavedova practically crawled inside Milos Teodosic’s jersey to deny him the ball and his hand-checking caused the Serb to angrily swat at him several times.

In January, the 6-foot-4 Dellavedova was voted the “dirtiest player in the NBA” in a Los Angeles Times poll of 24 players, coaches and assistants. He’s not dirty. He just plays defense the way it’s supposed to be played — hard and physical and relentless. He fights through screens like his paycheck depends on it.
