You have to choose. you can't say Colby isn't that good. while calling Usman P4P number 1. I find that a lot of posters have the idea that colby isn't all that after how easily he handled masvidal. It's understandable though, Masvidal himself is definitely not what he's been hyped up to be despite being an above average fighter himself.
Usman has been stellar as of late. A breath of fresh air to have a champion to defends often and is active. However he has only face 3 opponents in the last 3 years. Colby, Burns and Masvidal. before that, Maia, RDA and Tyron. This leaves his record eerily similar to Colby which many seem to be on the fence about his status as the definitive number 2 welterweights.
Personally, I've come to grips with the fact that Colby's competition as of late is less than stellar at WW, And by extension so is Usman's, since they are very similar.
I personally think it's bat shit insane that Usman is considered p4p number 1 in the sport (should be Volk or Izzy) Colby is Usman's best win x2, and I think generally most will agree with that.
So my mind has been made up.
Usman is the definitive number 1 welterweight, Colby is number 2. but Usman's resume isn't strong enough to be P4P number 1. and this is not "in light" of Colby's victory over Masvidal. this is just a general statement that Usman's record is really not THAT strong and neither is Colby's. I can't say that Usman's record is the strongest in the sport currently. I wouldn't call him p4p no.1.
I know P4P is some fantasy shit, but being no.1 generally means something. it means this is the best fighter in the sport overall currently. I really don't think it's Usman nor should it be Colby if Colby had been the one to beat Usman twice.
