Most people would say that the best Oregon State wrestlers of all-time is Les Gutches (2x NCAA champ, 1996 Hodge winner, World Champion), however it is probably Robin Reed, whose career has a lot of myth and legend attached to it. Reed went undefeated from 1921-1924 and won 3 national championships. He pinned his way though the 1924 Olympics to win the gold medal. He actually won the Pacific Northwest Olympic Trials in 4 different weights. It was said he could pin every wrestler on the olympic team including the heavyweight. Below is a link to his story.
