Hell no.. Chagaev should never be on the big stage ever again.. He doesn't deserve to fight under the bright lights of HBO or Showtime.. He's a ESPN level fighter.
Haye would knock Chagaev out and it would be brutal. Chagaev has a more versatile offensive arsenal that includes an uppercut and punches just as or almost as hard, but with more speed. Haye would batter Chagaev and uppercut him or tie him up when he got close. Chagaev would take a beating, but would be knocked out spectacularly in the early or mid rounds.
I know but still on paper he was a world class opponent before the fight and now hes a complete bum that got exposed only because he lost to Vlad...
I'd rather Chag return to the 7th circle of hell known as the WBA title scene. I'd much prefer to see Haye vs Arreola, Haye vs Kevin Johnson, Haye vs Dimitrenko or even Haye vs Tony Thompson.
