Arne Duncan has got game.

The U.S. Secretary of Education, who co-captained Harvard's basketball team in the mid 1980s, has played in the past few NBA All-Star Weekend Celebrity Games. He's done well against less-than-stiff competition (he's played with or against celebrities like Snoop Dogg, Mike Greenberg and J.B. Smoove).

But the 6-foot-5, 49-year-old's hoops resume got a legitimate boost last weekend, when he and his teammates won the 2014 USA Basketball 3x3 National Championship. Duncan teamed with former Northwestern stars Jitim Young and Craig Moore as well as former Princeton big man Mack Darrow.

Unlike in the All-Star Weekend Celebrity Games, players weren't taking this competition lightly. The USA Basketball tournament winners will go on to compete at the 2014 FIBA 3x3 World Championship from June 5-8 in Moscow, Russia. While it's unclear if Duncan will be playing then -- relations between the American and Russian governments aren't exactly rosy right now -- the prospect of representing the United States surely brought out the best in the competing teams.

“It’s been absolutely amazing, a dream come true,” said Duncan, who played professionally in Australia after graduating from Harvard as an Academic All-American. “We lost our first game so we didn’t even know if we were going to make the playoffs. We had to win our last game to win the whole thing; it’s unbelievable. They (USA Basketball) ran a fantastic tournament; we've played in tournaments all over the country but nothing like this, this is something I’ll never forget."

You can see highlights of the gold medal game in the video below. Duncan is wearing the No. 64 white jersey (which may be a reference to the year he was born, 1964). His defense is questionable, but his offensive fundamentals are sound and he produces some impressive assists.
