In 2007, Arthur had 13 points, 12 boards, and 2 blocks against KSU in Manhattan. K-State lost by 9. They didn't have any post pressence that year. That would have made a huge difference.
In the 2007 Big 12 tournament game that KSU lost to ku by 6, Arthur had 8 points, 3 boards, 3 steals, and a block in 17 minutes of play. I think that made a positive impact on the game for ku. Winning that game would have put KSU in the NCAA tournament, guaranteed.
