Keith 'One Time' Thurman has the unfortunate reputation of being of a ducker of Errol Spence. However, this us the furthest thing from the truth. When Thurman won the WBA (Regular) belt, challenged Floyd the WBA (Super) for unification. Floyd did the ACTUAL ducking by not fighting Thurman (who was his mandatory) to fight Berto. He then insisted that Thurman fight unknown prospect by the name of 'Errol Spence'. Thurman rightfully didn't accept the offer as Spence was an unknown prospect with no belt & no name. Floyd would retire soon after, leaving Thurman in the dark - officially ducking him & robbing him of a career high payday & a legacy fight. By the time Spence actually won a belt in 2017, Keith Thurman (now a unified champion) was injured & out for over a year. Therefore, the fight couldn't happen. When he came back, he was rusty & it showed in his comeback fight against Josesito Lopez. By then, Spence wasn't interested in Thurman & was fighting Garcia. Thurman would go on to lose against Pacquiao. Spence then beat Porter to become a unified champ. That concluded the Thurman-Spence saga. So this just shows that Thurman couldn't have ducked Spence & the fight likely woukd have never happened.
