I could honestly see them fighting for the belt in 2023, maaybe 2024 knowing how damn slow this division moves.
From Aldo pullouts, to Conor winning & never defending, to Max pulling out of UFC 222 & 226, to Volk not defending in over a year, to contenders like Zombie(past mostly), Yair, & Zabit being completely inactive for years at a time.
I would pick Evloev to win today, but I feel like Topuria has a higher ceiling. He reminds me of what Bektic was supposed to be.
