In his last major performance, Julio Cesar Chavez Jr. (51-3-1, 33 KO) put forth an extremely poor showing in getting dominated for 12 rounds by Canelo Alvarez. Chavez gave little effort to win the fight, it seemed, and the loss took away almost any shine left on his name. Since the May 2017 fight with Alvarez, Chavez has only fought once, knocking out little-regarded Evert Bravo. For reference, Bravo had been knocked out in three of his previous four fights before facing Chavez.
Daniel Jacobs (35-3, 29 KO) is another story. He too lost in his shot at Canelo, though he made the fight competitive. In fact, since returning from a battle with bone cancer, Jacobs has compiled a 13-2 record with the only losses coming against Canelo and Gennadiy Golovkin, the two defining middleweight champions of the era. In both fights, he kept matters close on the scorecards, giving a good account of himself.
Jacobs currently sits as a -1600 favorite at MGM with Chavez a +800 underdog. Those represent much longer odds for Chavez than he faced even in facing Canelo.
