What happens once Francis fights again? He should then resume his #1 rank. He’s the lineal champ.
Simply having and winning a fight doesn't just make you #1 in the world.
Francis beating Ferreira who is 20 on Tapology and 10 on Sherdog and Fight Matrix. Beating him is not the same as a #1 contender level fighter. Assume Frank beats Ferreira, then who is next? Meanwhile Tom is fighting much higher level of competition. Same as why Jon isn't the top HW IMO. He has 1 win ever at HW and it was a perfect style match up for him. Almeida, Volkov, Pav, Tom, Blades would all give Jon more trouble.
Frank just beating fighters isn't enough to be #1 in the world. Sure he is the Lineal HW champion and maybe he retires with it but not fighting or dropping to a much lower level of competition doesn't mean you keep your #1 rank. If GSP comes back and revives TKO MMA and fights regional level WWs is he #1 in the world again?
What you think of the HW roster in the PFL. There have been MLB players who went "Down" to lesser leagues like Nippon League in Japan or NHL players who went to the KHL in Russia. The PFL has had some decent fighters and Bellator had a few as well but even combined they don't have the depth that the UFC has. HW is very thin but the UFC does have more ranked HW then anywhere else.
Calculating rankings seems to be all over the map.
Tapology's rankings vary from Sherdog's and they vary again from Fight Matrix.
Its curious who they all vary and have different ways of calculating their spots.
Everyone has Tom #1. Tapology has Frank at #11 but the other two don't have him ranked. Fight Matrix is supposedly calculated with some formula but they have Nemkov #7 yet he has only 1 fight at HW??? Sherdog is massively biased towards the UFC and have Tom and Jon 1 & 2 as they automatically tie the UFC title to the top spot.
