Hagler could box, brawl and just beat you up if he chose.
Marvelous Marvin Hagler may not be the greatest middleweight of all time, though he's certainly in the discussion, but there is little doubt he is the most exciting.
Hagler (62-3-2, 52 KO) was able to box you, fight you, out-think you and beat you up. He had great power in both hands. He held the undisputed middleweight championship from 1980 to 1987 and holds wins over some of the greatest fighters not only of his, but of any, era.
Those include, of course, a unanimous decision over Roberto Duran and a third-round TKO of Tommy Hearns, both to retain the undisputed middleweight championship.
Hagler's lone loss, after rising to middleweight dominance, came in highly controversial fashion against Sugar Ray Leonard in what would prove to be his final fight.
The fight remains disputed to this day, with wildly divergent opinions about who actually won, as Leonard secured a narrow split-decision victory. Ringside opinion was mixed and scores ran the gamut of opinions from a convincing victory for either fighter to a close could-go-either-way contest.
