As a ninth grader Sims began training with the San Clemente Jets, an amateur wrestling club where kids from all over California came to learn freestyle and Greco-Roman techniques.

His kidney and spleen had been lacerated and his kidney had been nearly severed.
Sims worked delivering groceries for a while but defied doctors orders to start wrestling again. He went to the Olympic Trials and in the best-of-three finals, Sims beat Chris Saba of Colorado Springs, 5-2, in the first match. Saba won the second match, 4-0. Sims won the final match, 3-1 to make the Olympic team. [2]
