Floyd is the best welterweight at this time. If he was to fight JMM or PAC at any weight below 140, it is a different story. He can be beat over 149 and below 140.
He beat JMM simply because JMM is a natural lightweight. If he was to go down in weight the fight would have gone a little different to me. Maybe Floyd would have still won but not as convincingly.
Floyd is simply fighting fighters that are not lagit WW. I think Pac can beat him but has to be bolow 140 lbs.
I don't think Shane can stop him at this time, maybe a few years back but not at this day and age. In other words Floyd is the best P4P WW at this time.... My strong opinion
