DeMarco fought Broner as well, at a time when DeMarco was a little better, and not as young or green. Valero didn't do worse to him than what Broner did.
I would agree that yeah, Golovkin's resume is better than Valero's. The Ibeabuchi ****ogy doesn't even make sense. Valero had 30 fights. Ibeabuchi fought better opposition in Tua, and Byrd, in 20 fights, still an up and coming guy. As a matter of fact, Golovkin hasn't fought the equivalent of that version of Tua, or Byrd, yet.
