After defeating Canelo, is Crawford the best fighter of his generation?

LAS VEGAS -- It's time to have a serious conversation about where Terence Crawford belongs in the conversation of the greatest fighters of all time.

Crawford, 37, thoroughly outclassed Canelo Alvarez , and earned a unanimous decision victory to become the undisputed super middleweight champion. With the win, Crawford enters an exclusive club as the first men's boxer in the four-belt era to earn undisputed status in three weight classes (junior welterweight, welterweight and super middleweight). If he decides to hang up the gloves after Saturday's performance (and who could blame him if he did) he would retire with a 42-0 record with 31 knockouts, a five-division world champion (undisputed in three) and a victory over the man widely considered the face of boxing with relative ease.
