Bobby Portis said last month he wanted to be "the greatest Razorback of all time" when his basketball career at Arkansas was finished.

The finale came Tuesday when the 6-11 sophomore said he was declaring for the NBA after a standout season that saw him named the Southeastern Conference Player of the Year.

"Unbelievable experience for me at the University of Arkansas these past two years," Portis wrote on his Twitter page. "The love I have for this program is unconditional, but I've decided to forego my junior year of college to take that next step and entering into the NBA draft."

Portis, the key cog in Arkansas' rebirth under coach Mike Anderson, averaged 17.5 points and 8.9 rebounds this season, leading the Razorbacks (27-9) to the NCAA tournament for the first time since 2008.

Good news for Shockers fans

Wichita State has already scored a big victory for next basketball season.

Guard Ron Baker and Fred VanVleet announced they will return for their senior seasons for the Shockers. The announcements come weeks after coach Gregg Marshall turned down a chance to leave Wichita to coach at Alabama.

Baker and VanVleet applied to be evaluated for their NBA draft potential. They issued separate statements saying they wanted to return to try and lead the Shockers to an even better season than this year, when the Shockers finished 30-5 and defeated Indiana and Kansas in the NCAA tournament before losing to Notre Dame 81-70 in the Sweet 16.

Baker led Wichita State in scoring, averaging 14.7 points per game, with VanVleet second at 13.6 points per game.
