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.
I mean struggling relatively to how he's looked against opposition in the past. His power hasn't seemed to have quite as much effect on his opponents as it did at lower weights, the shots these 122 guys land seem to move him more than usual.
