I would add Vernon Forrest (RIP) to the list as well and I do not think Keith Thurman would beat him either.
Depends which Marg I guess. Pre Mosley Marg (who was allowed to use plaster) stops Thurman but the Pacquiao Margarito loses wide
Everyone saying Thurman beats JMM have me wondering. If Josesito Lopez and Luis Collazo and Pacman can score a bodyshot KD (or have Thurman on q***r streer) why couldnt JMM?
My opinion has soured so much on Thurman in recent years. You have to be an absolute dog to beat even some of those guys, let alone all of them. Thurman is no dog unless he's getting beaten like one by 40-year-old Manny Pacquiao, against whom Jeff Horn made a better account of himself than Keef. Loses to all of them the same way his career is petering out; with a whimper.
He got punched in the face by Leonard Bundu and has been on the backfoot ever since. Until that fight he was "One-Time". Some baddass boxer puncher. Leonard Bundu changed his life. That's when he started practicing yoga and learning to play the flute.
