1) Gaethje because that's an easy fight for conor and actually a lot easier than Cowboy even though Gaethje koed Cowboy, stylistically Cowboys the harder fight for him (mma math doesn't work, styles make fights)
2) after koing Cowboy and Justin he fights the Khabib/Tony winner for the lw strap
3) if he wins that he fights Masvidal for the BMF belt and possibly the welterweight strap (both belts) if jorge happens to fight and beat kamaru by the time conor beats khabib/tony
4) now if he happens to win that he would fight Nate Diaz in a trilogy fight putting the BMF belt and WW strap on the line
if he can pull all of that off then theres no denying how good he is. will it be challenging? fuck yea and he has to beat cowboy first before he even has the chance of sniffing any of these fights, if hes not lying about how serious he is, then theres a chance he can pull these off hes been doubted before and proved the world wrong against legends like aldo and alvarez so theres a big chance he can shock the world and prove the world again
