Quartey naturally the favorite, but not enough evidence either way. Receiving one punch, and being able to take it no less, hardly is a defining proof
There's no more than enough evidence to suggest that the mid 90s Quartey fucks up Thurman badly. And this is coming from a man who roots for Thurman and thinks Ike is historically overrated. But he was a lot better than Thurman.
Same as Xplosive, I think Ike is pretty fucking overrated (who did he beat, Cool Vince?), and I actually think Keith is a little underrated on Fightbeat. But Ike is clearly the more solid, more skilled fighter, he'd win.
