I will go back many years, but the all time best wrestler from Kansas is Myron Roderick. He was a 2x state champ from Winfield and a 3x national champ at Oklahoma State. He also was 4th in the Olympics. After he finished wrestling, he coached for 13 yrs at Ok. State. His teams won 7 national championships and had a 140-10-7 record. He is a member of the Wrestling Hall of Fame.
For more recent wrestlers, Scott Coleman from Manhattan was a 3x state and 1x national champ. Kenny Fischer was a 3x state and an all-american at OU.
