Toughest fight for Inoue at 126?

I'd hope so.

 

126 will be a tougher challenge for Inoue than 122 that's for sure. I think it's a deeper division with better fighters, Fulton was never a threat but Inoue could be in for some tricky fights at 126.

Ramirez I suspect will be his toughest test. He's defensively responsible with that tight high guard and is a good counter puncher but I think he's a little static and might struggle with how well Inoue moves.

Lopez is an awkward fighter, can be unpredictable with some of those wild swings and he's pretty damn explosive, Conlan learned that the hard way. But he's often has his hands down, that might work well vs slower fighters but Inoue is so fast and accurate, it will likely cost him vs the Monster.

Figueroa is a tough style match up for a lot of guys with his size and work rate but I think Inoue will make quick work of him, unless Figs has a chin that can take Inoue best but even then good chins can get cracked if hit often enough and I suspect he will get hit a lot vs Inoue.
