I would disagree with this a lot. Olivares has a great, great list of wins and didn't really start losing until his party lifestyle caught up with him and he couldn't make weight well. He lost to Chucho on a cut, and Herrera while badly drained in his final fight at 118. That's it, and he beat Chucho twice anyway. Above 126, he did pick up much more losses; partly due to him aging, the lifestyle, growing more inconsistent and being the smaller guy but he has a couple of very good wins there too, and was winning on the cards against Arguello before getting nuked.
