Sure, Terence Crawford's the undisputed welterweight champ, but out of his 40 professional fights, the only legit threat was Errol Spence ... so says Canelo Alvarez who tells TMZ Sports he respects the dude a great deal, but their resumes aren't comparable!
Obviously, Crawford (40-0) has been the talk of boxing since his TKO win over Spence on July 29, with many calling him the face of boxing, and the world's best pound-for-pound boxer.
Since then, Alvarez has been hounded with questions about whether he'd fight Crawford.
