Tavares is better than Gray at this point in their careers
Tavares is a good grappler who has grapplefucked guys like Omigawa, Gamburyan, Fisher, Black, Peralta, Weichel, Guida etc. He drew with Lentz, beat Stout in a close one, shouldve got the decision against Tyson Griffin and has only really been dominated by Khabib before fighting Choi. He got KOd by Wiman but it was a back and forth FOTN, and he was winning against Roller before he got caught by a combo in the 2nd
He was supposed to test Chois gurappling, tried to grapplefuck him (and he's better at that now than Gray) and failed and got KOd easily in a couple minutes, along with Khabib the most dominant loss of his career. It was a VERY impressive performance.
Choi will need to fight a more well rounded and durable opponent soon but ATM a fight with Cub makes too much sense not to make.
