Julian Jackson 1990 version Tommy Hearns 1987 version Sumbu Kalambay 1987 version Nigel Benn 1990 version 12 rounds ,match em up as you may .
Hearns would be the favorite without a doubt, although, Benn and Jackson have a puncher's chance. Kalambay doesn't match up well with Tommy, but Kalambay would school Benn and Jackson. Benn vs Jackson is a crap shoot, but I favor Julian because he had much better technique than the 1990 Benn.
I got it same ,Tommy out boxing Kalambay ,though its close in parts Benn and Jackson have a mini war with both being rocked to their toes,but Nigel putting him down for the count in 6. Benn and Hearns in another mini war but this time its Tommy sending Benn down and out .
