That's another myth perpetuated by K-State fans. Hinrich was on the olympic team. Collison is a solid player for the Thunder. Chalmers is starting for the Heat. Gooden just had a big year for the Bucks. Arthur had a big year for Memphis last year before an injury this season. Rush just had his best NBA season with the Warriors. Aldrich is developing for OKC. Markieff had a really good rookie season with the Suns. Marcus is still setting into his role in Houston. Henry is getting minutes with the Hornets. Julian was kind of a bust. D-Jack has been a role player for a few teams, and Selby is a project with the Grizzlies. Pierce is the only super star, but collectively, that's a pretty good list of NBA talent.
Edit - forgot to mention that T-Rob will be a top 5 pick and Tyshawn will probably be an early 2nd rounder.
