Schoonover, a 5-foot 11-inch 200-pound bruiser, was named Sahuaro's Most Valuable Player both his junior and senior years. He was a two-time first-team All-City section and the offensive captain his senior year after he became the third Tucsonan to rush for more than 1,000 yards in two consecutive seasons. Former Sahuaro coach Virg Stan believed Schoonover, who led the city in rushing as a junior and went on to play at Hawaii, was the best fullback Tucson had ever seen to that point. "I've seen fullbacks in this city since 1956 and I don't think there's anyone who comes close to his caliber," Stan told the Arizona Daily Star in 1972.
