That's because Evloev currently fights the toughest competition available in his division while the champ fights favorable match-ups like Holloway, Rodriguez and KZ. Evloev would finish all of these guys.
Volkanovski vs Allen or Evloev would be very competitive, simply because these are men in their physical and fighting prime, not people that have their ranking because they are marketable and have been around a long time or rank squatted after a win (Yair)
Remember when you lost to the champ and dropped to rank #10?
Holloway can now lose 10 times to Volkanovski and stays ranked at #1 LMAO
UFC matchmaking is so shit that we watch Allen vs Evloev go at it, which is a phenomenal fight, but we will never get to see Max or Volk fight the new breed that is in their prime rn.
Instead we get a shitty fight for a shitty fake belt.
