Bettmann/Getty Images The relentlessness Pryor displayed against Arguello created the ultimate modern boxing near-miss. Despite Pryor coming up while Leonard, Duran, and Hearns fought at welterweight, the tenacious junior welterweight did not score a fight with any of them as a pro. While prior Leonard-Pryor negotiations broke down over low offers to the less famous fighter, the two reached an agreement to vie for Leonard's welterweight belt in 1982. Leonard soon suffering a detached retina in a tune-up fight threw off those plans. "Hawk" moved on to Arguello later that year, but Leonard's first retirement took a fight with boxing's star of the moment off the table, altering Pryor's career.
