Are you unable to read English ? Is it that hard for you to understand the words "I concede" in my prior post ?
I've made the point that Floyd was brought along like any young prospect in the early days of his career.
His first notable fight was Gennaro Hernandez and before that, he beat 16 or 17 tomato cans. That's par for the course and not much out of the ordinary.
Therefore my "concession" to you is regarding the fact that the training wheels came off relatively early for Floyd, which is a testament to his skill and ability.
Yes Marquez ultimately became a Welterweight, but in 2009 I don't think he was quite ready to fight at 147 lbs. let alone 142 lbs.
The same goes for Canelo, where I would have liked for them to have simply fought at 154 lbs.
In neither of those cases would the weight have made a difference in the outcome, but it's a personal preference thing.
I'm going to say this once and once only. Stop looking for a fight where there's none to be had.
