ok here goes

1 Lennox Lewis is a top 10 all time heavyweight champion
2 had hamed met barrera in their super bantamweight days and hamed was still being trained by brendan ingle then barrera would have been KOd. hamed in his prime would have also beaten the likes of pacman and morales
3 bowe in his prime (against holyfield 1992) would have had a chance against heavy in history
4 tyson with kevin rooney in his corner would have beaten any heavy in history
5 hearns would have beaten hagler in a rematch

i think thats enough danger now
