Agree with all except 'beat Jan connivingly'.
But yeah, he's getting close to it I'd say. Israel obviously has some defences racked up but most of his good-great wins were in terrible fashion, and just sort of avoidance tip-tap BS 'fights', where, okay he technically... prolly won, but... to me it's how you win too. And a champion or a GOAT should win in style and no questions asked, not just 'ehh, I guess?'.
The Adesanya fight and win was terrible. The Yoel fight was abysmal. Costa win was great but Costa hardly a great is he... Um, who else... Whittaker x 2 is probably his best win, but second win he kind of struggled, which makes the first look like a bit of a fluke.
