I was just looking through Julio Cesar Chavez snr's boxrec record and I found a Tony Lopez. He appeared a deserving challenger for the Mexican with penty of good names on his record like wins over Rocky Lockridge twice, John John Molina twice, Jorge Paez, Larry Lacoursiere and Greg Haugen. I have a lot of interest in Julio Cesar Chavez and was wondering how many of his defences were against deserving contenders like Lopez? Did he often defend against people outside the top 10 of his division or did he regularily seek the best.
