Who is the best? To be honest, my knowledge doesn't really go any further back than Lennox Lewis so it would be interesting to know who everyone thinks is the best ever.
England/Britain has no real claims to Fitz who is not the best anyway. many would say kid lewis on his many acheivements & era, but he wasn't alone there... some would argue Wilde or Lynch or Berg or Welsh and such Graham wasn't even the best MW nevermind best fighter. McAvoy, Gilroy, Randy Turpin, Benn, Watson and so on... some might say LL, but does Canada have more right to him? maybe. Truth is there are many, Jim Driscoll, Owen Moran, Joe Bowker, Alex Lafferty all equally great fighters. Point is it's damn near impossible to claim one over an other at the Very Top. but if one boxer truly embraces it ALL for British fighters, for me that's LEN HARVEY!
It's impossible? The best h2h? The best achievement wise? The best being most consistent? The best being most high class wins? The answer is different depending on the parameters of the question.
born here, moved away as an infant. learned to box in NZ & Aus, fought much of his career in America - We have No Claim to him!!!
I've read as young as 2, so what was it then... still his boxing has FA to do with Britain we have no claim to him!
Naseem Hamed should definitely be involved in the discussion. Amazing fighter when he was motivated and in love with the sport.
