Andrew Wiggins brings LeBron James out of his seat with poster dunk attempt (VIDEO)

Presumably, LeBron James does not impress easily. So when Canadian basketball phenom Andrew Wiggins does something on the court that brings the greatest basketball player in the world to his feet, it has to be shared.

With the U.S. Olympic team watching on Sunday, Wiggins showed off his full repertory while playing against other highly touted high schoolers during the LeBron James Skills Academy camp in Las Vegas — a falling-out-of-bounds three-pointer with a defender in his face, strong takes to the basket and dunks.

The crowning touch wowed King James. With James and several of Wiggins' future NBA contemporaries watching from baseline seats, the Thornhill, Ont., native tried to posterize a defender with a tomahawk dunk. He was fouled before he could throw it down, but it brought James to his feet.

It's not like there's anyone who doesn't know Wiggins is considered a can't-miss future NBA lottery pick. Neverthless...

Small wonder Wiggins is considered the best high school player in North America. It's possible that he might fast-track high school so he can go to college in 2013 rather than 2014. His top five schools are Kentucky, Duke, North Carolina, Syracuse and Florida State, which is Wiggins' parents' alma mater. The last three first overall NBA picks have come from either Kentucky or Duke, which probably helps their chances of getting the Canadian wunderkind.
