If your British and a fan of boxing you should know what Buchanan did. He's one of the best we've ever produced and one of very few great fighters we've ever produced that the Americas rate, thats because he travelled and fought the best. Technically he was outstanding, and tough as nails. P4P/prime for prime he beats all the Brits from 80's till now bar Lewis. Buchanan beats, Naz, Ben, Eubank, Calzaghe, Hatton, Froch, etc, etc.
If Amir Khan said this..? he would be getting so much abuse. David Haye has never compared him to past fighters, i think its disrespectful to do so. Its like speaking about somebody when they cannot defend themselves inside the ring. Benn, Eubank, Calzaghe, Watson none of these guys can really defend against Froch's statements! Maybe only Calzaghe if..? he comes back. I have never heard David Haye, saying he was better than Frank Bruno or Lennox Lewis. They tried to bait him on ringside about the 70's fighters, and David Haye modestly just said they would probably beat him, referring to Frazier, Norton, Ali etc.. Seriously fair play to Froch taking on all comers, but i honestly still put David Haye ahead of him on current achievements. Carl Froch has never been undistuped at Supermiddle Weight and has never been "The Number 1 fighter at super middle weight"... Joe Calzaghe was undisputed and Number 1. David Haye was undisputed at CW and Number 1. And still the jump from CW to HW is not a feat to be overlooked, only David Haye and Evander Holyfield have did it! From CW!
