In the last 30 years I think 8 Kansans have gone to the NBA (Steve Henson, Gaylon Nickerson, Wayne Simien, Matt Freije, Earl Watson, Paul Shirley, Muarice Evans, and Danny Manning -- and Manning wasn't really from Kansas). There were some other Kansans from that era who shone at the college level: Taj Gray, Val Barnes, Kris Weems, B.J. Williams, Manny Dies, Perry Ellis, Cauley-Stein. Semi could be one of these guys, I'm sure. I'm also sure I'm missing 3-4 others.
That's about 20 high-quality players in 30 years. Only three went to KSU. Only four went to KU, and that's counting Manning, who transferred to Lawrence High as a package deal with this dad.
It would be very nice to just count on this level of player going to KSU, but surpisingly enough neither school really has the state "locked down."
