In what sport did Dan Gable win all six of his matches at the 1972 Olympic Games?

Gable is an icon and universally loved in his home state of Iowa, he competed as a student at Iowa State and created a wrestling dynasty at the University of Iowa.❤

key word in the question was "matches"

being an Iowan, I'd better know this answer.

I got lucky I voted based on his looks, he looks like a wrestler
