Based on lara last 2 fights, canelo will beat him. Lara doesn't throw a lot of punches. He basically waits for counters. Trout is a proven fighter by beating cotto while lara best win (he lost but was robbed badly) vs decline shot Williams who was coming off a ktfo terribly to Martinez.
This has nothing to do with what I said. My point is that you have to consider everything going into a fight. Having a strong chin is an obvious advantage. That means that you have better chance of not touching the canvas or possibly get KO'd, if you get hit flush. It's real simple to understand.
I used the word suspect as in "suspicious", "not sure", "not knowing". I didn't mean it as if I knew for a fact he had a weak chin. But since you're already certain he doesn't, then I guess you shouldn't worry about it then. I think it was the same with Rigo. I personally didn't say he had a glass jaw or anything like that. I just didn't know.
