You don't become the WW #1 contender by winning a fight at MW. There is no amount of mental gymnastics Kamaru or his management could use to justify denying Leon a title shot again.
The great thing is though once Leon becomes champion he will be well within his right to hold the misdeeds of Kamarus agent against the contenders currently represented by that agent. So Vicente Luque, Gilbert Burns , Belal Muhammad, Khamzat Chimaev, Muslim Sahlikov should not be expecting to get a title shot anytime this decade.
Maybe in 2030. Also why are Gilbert Burns and Vicente Luque not fighting eachother?
