A very good list, although he missed to include Flyweight, which should have Jimmy Wilde as best fighter.
Jones was BETTER at 168 than Calzaghe in terms of ability, Calzaghe was GREATER at the weight in terms of achievement. Greb is a tricky case since he had such an amazing resume, but the only film of him is some really sloppy sparring.
he doesn't have the best resume at the weight and you can argue as much as you want who was going to win between him and Ali but you can not prove it. What is certain is that Ali beat more HOF and ATG in their primes
So am I the only one that noticed they completely skipped Flyweight? Apart from that, probably the best list I've ever seen on that dreadful site. Galaxy ain't the #1 Jr. Bantam, though.
