I think he would have beat Froch, Kessler, taylor by brutal KO but aint so sure about abraham ,ward and direll
Brutal KO? He couldn't punch. Collins was very, very brave and very, very tough. His fights with Watts, Thornton and Pyatt show world-class boxing ability on his part. While his fights with McCallum, Eubank (second fight), Benn (both fights) and Reggie Johnson show an effective marauding warrior at the highest level, albeit with poor technique. His best performance has to be the big Eubank win at Millstreet, in which he countered the counter-puncher in Eubank but without a defense, something deemed impossible. Only Michael Watson in their first fight had taken everything Eubank had and countered it, but did so on his arms and gloves mostly. While Nigel Benn countered Eubank in their rematch but with an incredible ammount of ducking, slipping and weaving. For every punch Eubank threw at Collins he found two back in his face. If Eubank didn't throw, Collins would lunge and exchange and outwork. It looked very difficult to master Collins that night - Eubank didn't have the height or reach, whereas Froch and maybe Kessler would?
if by brutal ko you mean moderate knockdown which they get up after 12 seconds then yea..........high five?!
I think Collins would have done well, as said he was tough, and would have put alot of pressure on whoever he fought, he also had good victories over the big punching Nigel Benn. Its hard to call some fights that will never be, but I could make an argument for Collins against any of them, here goes against Froch - Collins on points Kessler - Collins close due to styles, Abraham - Collins to outwork Abraham at 1st only for Abraham to come back into it for a close fight which could go either way Taylor - Collins to wear him down with pressure and win by stoppage Dirrell - Collins wide on points based on the Dirrell/Froch match, Collins would cut the ring off and rough Dirrell up in there Ward - alots made of Ward due to one victory, but Collins would know how to rough up Ward and fight on the inside. I havent seen enough of Wards fights to really imagine it so will have to skip this one
Oh and he also had a granite chin. Took Benn's best left hooks without blinking an eyelid.... Reggie Johnson threw everything at him and couldn't get him over or get him stopped.
To be honest I don't know. I'm thinking Froch's height and reach would do well though, and Kessler's technique.
