Islam is probably the only one who is definitely the best in his division. Aspinall might be better than Jones, Ankalaev might be better than Pereira, Izzy and Strickland could beat DDP, Leon probably wouldn't be a heavy favorite against most of the top 10 or Islam, Topuria might be the best, but he's beaten 2 old guys coming off losses, so let's see if he can beat Max, not sure O'Malley will be a heavy favorite against Merab, while Islam is the huge favorite against everybody at LW, and might even be favored against Leon. He's also finished 6 of his last 7, and the one decision was FOTY.
Style wise, Aspinall and Poatan are fun to watch.
