As a student-athlete at NU, Kraft competed in the 167-pound weight class, winning the 1957 Big Ten Title. After graduation, Kraft took over the head coaching duties, compiling a 128-106-5 record in his 22 years at the helm. During that time, he coached 14 All-Americans, two of which were national champions.
One of Kraft's greatest contributions to the wrestling program was the founding of The Midlands Championships, now in its 55th year. The Midlands brings the very best in amateur wrestling to Welsh-Ryan Arena every December between Christmas and New Year's.
Kraft also spent time in front of the cameras as a commentator for ABC's Wide World of Sports during the 1972 and 1976 Olympics. In addition, he has served on the U.S. Wrestling Federation Governing Council and Executive Committee, and was president of the association from 1972-76. In 1998, he was inducted into the National Wrestling Hall of Fame.
