No worries, bud.
Sure, I don't think they'll give him a good grappler any time soon, but he'll have to face one eventually. Also, Izzy could lose to Bobby and then a rematch with Izzy won't necessarily have to take that long, unless they want to make a trilogy fight with Bobby right away and Izzy becomes champ again. And even if he wins, I could see them making the rematch with Pereira sooner rather than later and not give him too many fights to climb the ladder.
But we even have to see if he can handle a middle of the road calibre grappler/rassler, let alone a great one.
It's all good, bud. I lol'ed at the rinnegan comment.
