In the MW division, Israel Adesanya.
In the LHW division, it would be Corey Anderson and Johnny Walker.
In the HW division (in order of importance), it would be Stipe, Ngannou, and Lesnar (just because the Lesnar fight has been teased for a while and it is the biggest name on the list, so casuals who tune in for this big fight would just Google Jon Jones' record and unhesitatingly call him the GOAT based on the numbers without necessarily knowing whom he actually fought).
Six individuals. The least interesting are the ones in Light Heavyweight, but if he wins those, he will have indisputably cleared out the division.
