Running Back-Kick Returner
"Calhoun started at fullback against the Jets on the road and was the game's leading rusher with 71 yards on 18 carries. He ranked fifth in the final ground-gaining statistics with 88 yards on 21 tries, caught two passes and returned six kickoffs. One of only two Buffalo rookies to appear in every 1974 game, Don's longest run of last season was 15 yards (against the Jets) and his longest kickoff return was 25 yards (against the Jets in Buffalo). Don has excellent quickness.
He gained 1,300 yards in his varsity career at Kansas State, leading the Wildcats in rushing as a junior. His 1972 rushing total of 608 yards was the fourth best in the school's history. Don's best day in college was 132 yards on 16 tries against Brigham Young in 1972. A halfback as a sophomore, he played fullback his final two seasons. Don led the Wildcats in kickoff returns as a sophomore and as a junior, finishing with 669 career return yards.
Don majored in physical education and recreation. He enjoys basketball, a sport he played in high school, as a hobby."
