Richie Woodhall, Robin Reid, Carl Froch and David Haye all won Olympic or World medals. Chris Eubank beat Dennis Milton and Ray Rivera in New York, both Pan American Games medalists. Although Woodhall also beat Rivera at the Olympics. Nigel Benn demolished future Olympian Mark Edwards and former Olympian Rod Douglas en route to the 1986 ABA title. The question is whether Lennox Lewis counts considering he never represented GB as an amateur. Any others?
Alan Minter, olympic medal and undisputed champion. ?Chris Finnegan, Gold and a definite world title if he had a dozen belts to go for. ?Pat Cowdell, prob could have won a WBO Super Bantam belt had it existed. Seems no Brit has ever won a gold for Britain and then become an undisputed champion, it's up to you Degale.
