LAWRENCE, Kan. -- Kansas freshman Andrew Wiggins made official Monday what he's been telling folks all along: He's headed to the NBA after his only season with the Jayhawks.

The 6-foot-8 forward, who was voted second-team All-America earlier in the day, is expected to go in the top three picks in the June draft. Many believe he could go first overall.

"It wasn't an easy decision because the fans showed me so much love here," said Wiggins, choking up briefly during a news conference at Allen Fieldhouse. "I just wish I had more time. College goes by so fast. I can see why people stay all four years."

Wiggins was the top-rated recruit when he arrived at Kansas, and his brief career was a bit of a roller coaster. He struggled early in the season, caught fire midway through, and then flamed out when it mattered most in an NCAA tournament loss to Stanford.

Wiggins only scored four points on 1-for-6 shooting in the third-round defeat. Afterward, he said despondently that he let his team down with his poor performance.

That ultimately didn't have any bearing on his decision, though. He announced he was going pro while joined by Kansas coach Bill Self, his parents -- former NBA player Mitchell Wiggins and Olympic silver medalist Marita Payne Wiggins -- his older brother Mitchell Jr., and several of his teammates, including fellow freshmen Wayne Selden Jr. and Joel Embiid.
