DraftExpress has posted its latest 2012 Mock Draft. Jonathan Givony and company expect Myck Kabongo to stay, but J'Covan Brown to declare and get drafted in the 2nd round. Kabongo is currently ranked 31st overall in DX's Top 100 prospects list, and Brown is 61st. Similarly, ESPN Chad Ford's latest update has Kabongo at 29, and Brown at 74.
Keep in mind that Kabongo could likely improve his draft stock with an outstanding sophomore season (DX has him 5th in the 2013 Mock Draft), whereas Brown has likely maxed out his draft stock. In addition, Brown is a fourth-year junior thanks to being academically ineligible his first year. If Brown were to return, he could put together a Big 12 Player of the Year type season similar to Kansas State's Jacob Pullen and still not improve his draft stock.
Just food for thought as we wind down the 2011-12 basketball season.
