"Kim has a tremendous future in this business," Frank Haith, the head coach of Tulsa said. "I saw his future potential as a coach when he was a player for me at Missouri. Anyone who has met Kim sees his personality, and his ability to be an effective recruiter. He will be really good on the floor with our guys, and I think the sky is the limit for him as a coach. Kim will be able to use his experience of playing for me and lend his perspective to all of our new players, and really help speed up the growth and education process."
