Iron chinned workhorse with a brilliant ability to adapt vs. a low volume counterpuncher.... Yeah that's a real rough one to figure out. Not... Calzaghe clear UD.
Roy Jones, Michael Spinks, Bob Foster, Billy Conn, Archie Moore, Saad Muhammad, James Toney, Ezzard Charles, Carlos Monzon, Marvin Hagler, Dwight Qawi, Dick Tiger, Ray Leonard, Ray Robinson, John Conteh, Michael Nunn... all worse matchups for Canelo than Slapping Joe.
You literally just named every ATG you could think of without even thinking about styles, didn't you.
No, I just named a slew of better fighters than Joe... all with worse styles for Canelo in their own way. Unless you think that Joe is a worse matchup for Canelo than Michael Spinks or Bob Foster. Lol.
Calzaghe is better than Canelo, he should win a wide UD but would probably only get a draw from Canelo's judges.
I don't nessasarily think that but I also know you didn't have time to seriously consider all of those fighters styles and are just being a hater.
