Dupree also played on Philly High's basketball team, which finished 1979 with a 33-4 record and reached the semifinals of the Mississippi State basketball tournament. Still not enough? Okay, cool. Dupree also played first base and catcher for the baseball team, hitting .481 in his junior year. That same year he rushed for 2,550 yards and scored 34 touchdowns.

Career Recap: While his high school career was nothing short of amazing, the same cannot be said of his college career at Oklahoma and his short stint in the NFL. Dupree was hampered by injuries and after a standout freshman year at OU, it was all downhill from there. Despite not starting until the seventh game of the season, Dupree finished his freshman year with 1,444 yards and 13 TD's, this would be his last prolific year as a football player. The subject of an ESPN 30 for 30 film entitled, The Best That Never Was, Dupree was one of those rare cases of a standout athlete who for a multitude of reasons couldn't find his feet in the pros.
