Possibly. I think he's recently shown signs of struggling with the size of some of 122 guys already, so fighting two big 130lbers might be two steps too many.
Struggling is a strong word. He's had zero close fights. Floored twice for being cocky. Naoya reins in the cockiness and he does things like 12-0 his most deserving rival. If Nakatani doesn't answer some questions then perhaps a walking skyscraper like Espinoza will. Right now 130 is a dream. 126 will likely - sensibly - be the final pit stop.
