Andrew Wiggins has frequently been called the best NBA prospect to come out of high school since LeBron James, but some are questioning his motor and others like some of the other talented players in the anticipated 2014 NBA Draft.

"Until Wiggins learns how to play hard, he's Kansas' third-best freshman," said one NBA scout.

Wiggins "is not always playing hard and motivated," an NBA scout said. "That scares people. That scares me a little. You need a gym rat, someone that absolutely loves it. It's 82 games. It's tough. Those guys are harder to win with than guys who love it."

One NBA scout said Wiggins' "worst-case scenario" is Vince Carter.

"He's not LeBron," one NBA general manager said. "It's not his fault regarding all the hype. People say he's pretty humble. He's a top-three pick for sure, if not No. 1."
