Roy is years past his prime.
But he still wants it.
He has gone from the highest of highs(winning the heavyweight championship of the world) to the lowest of lows(back 2 back KO losses)
But he still wants it.
This is a man who seemingly has nothing left to prove. He has been the undisputed pound for pound king for well over a decade, winning titles from middleweight, super middleweight, light heavyweight, and heavyweight, all while making it look easy with his inhuman handspeed, impregnable defense, and virtuoso combinations.
He doesn't have that anymore. But what he does have is his heart and desire back.
No one is giving him a chance.
How is he going to decision someone that is so energetic, throws constantly, and has never been defeated in his pro career? How is he going to knock him out when he hasn't had a KO victory since 2002?
Roy is out looking to prove everyone wrong. This is what great fighters do when they summon that extra something inside of them and somehow manage to come out victorious when no one thought it was possible.
If Roy somehow defeats Calzaghe, what would it do to his legacy?
It's clear as daylight that Roy can't do the things he used to do anymore.
But he still wants it.
