I've watched some of Lopez' previous matches and I could say that he had a hard time beating some of his opponents. I think that's something that he should work on since they almost have the same record as Taylor. Though it is obvious that Lopez has huge potential though he's still in the process of establishing a good record. I hope he'll grab this chance to prove that his previous winning matches were not just won by luck.
Lopez has a record of 18 wins and 1 loss. A boxer can't just smash the 18 pro boxers by luck. He even beat Loma, that's quite a plus for Lopez, you can't be a nobody with a such win.
Taylor's last fight with Cattral was also controversial, people look at it as robbery. It would have been best to put an end to the doubts. Catteral would be a good fight and not the WBO's will for him to fight Lopez.
No doubt that he beat Loma, no question about it, but then again, Loma is not 100%, so maybe the outcome would be close or very different. Same with Lopez, he was in his prime, although one issues is that he has also a hard time hitting 140 lbs. And so was a narrowing decision win against Catterall. And they are supposed to fight for a rematch, but not going to happen.
So this fight could be another break for Lopez, or Josh Taylor winning but might be moving to the higher weight division because he might not make the 140 lbs if he insists to stay here. I haven't seen the odds but it might be close.
