College career
Henson began his college wrestling career at the University of Missouri, in Columbia, Missouri. He was coached at MU by Wes Roper. He chose Missouri because it was close to home, and because he wanted to prove that he could win for his in-state school. He proved the point by becoming a Big 8 champion, and an All-American in his freshman year, winning fifth place at the 1991 NCAA Wrestling Championships. He achieved this despite being the seventh seed in the tournament. Ironically, to win fifth place, he defeated second seeded Donnie Heckel, of Clemson University, by a score of 13-2. He then transferred to Clemson to wrestle under Coach Gil Sanchez. He ended his college career as the most successful wrestler in Clemson history, going 71-0 over his last two seasons. He won back to back NCAA titles at 118 pounds in 1993 and 1994. In 1994, he was also named ACC Wrestler of the Year. He then returned to the University of Missouri to finish his degree, graduating in 1995 with a degree in Park, Recreation and Tourism Management. He was inducted into Clemson's Hall of Fame in 2000. Henson was one of Clemson's last wrestlers and named one of ACC's Top 100 athletes in a conference more known for basketball.
