Duran would have given Arguello a fearsome beating. The fight is a stylistic nightmare for Arguello. Ad in Duran's naturally larger frame and strength and Arguello would have never been the same after the fight. Duran by KO in 5 to 8.
Right on on all accounts. I just don't see any way that Arguello pulls out this one. A more interesting fight involving Arguello that could have potentially happened is Salvador Sanchez. But a Duran fight is really not an interesting one, as it is a foregone conclusion.
