Ward, Loma, and Rigo. You can put them in any order you want. This list is based on the ability to exercise a high level of skill on top opposition.
It's all subject to opinion but here I go. Rigondeaux -who is ducked like crazy but, no one seems to care. Ward -who is daring to be great by moving up and fighting the boogieman of 175. Golovkin- who I named so that the brown shirts on this forum don't call me names for not acknowledging his dominance over 147.
Is racism still the name of the game on here? We have got to get over this. They want us to focus on hating eachother, so they can exert their dominance over us. Hate begets more hate, and more hate begets something worse. The best thing we can do as a society is adopt Jesus Christ as our Lord and Savior and try to live by his words. Love your enemies. That is the rule to live by. Things are getting bad and they are only going to get worse. I plead with everyone to turn to God.
Skills can be negated by a pressure fighter. See Salido and Loma. Lomachenko is vulnerable to pressure fighters because his power isn't a big enough deterrent.
He backed off after that first uppercut Brook landed, and Brook teed off. It lifted GGG of the ground, so that's a good indication he can be backed up. I think Canelo can get it done.
