PFL/Bellator keeps signing really good talent that's not Russian too though like Manoel Sousa, Jora Ayvazyan, Colgan, Meredith, Baki, Darragh Kelly etc etc. Even Ali Taleb was a flex. UFC is very bad at getting talent.
I suspect Aaron Pico beats Pitbull, which means he's going to be matched up with Khizriev most likely and then Khasan Magomedsharipov will eventually be in the wings. I kinda look forward to seeing Pico vs the Russians. I also would sign Mokaev and Severino immediately if I was them and open up a 125lb division.
