I'm actually kind of with you here. A lot of the guys who get KOd brutally by Inoue do so because they get caught moving forward and Inoue is very accurate and powerful, so it only takes one. Butler really seems to like to stick back on the ropes and run. He is a bit of a slow starter though from what I've seen so maybe Inoue can land a combo on him early. But I don't think Inoue will put him out in one blow or KO him in the midrounds. It'll be early before he gets going or later when he's starting to move a little less. It'll be good practice for Fulton.
Sultan is a multidivision champ and got schooled pretty bad, I feel B tier is a fair assessment. If you actually watch him fight he can be pretty good when he gets going. At least against a very one dimensional puncher like Sultan he looked very nice, much better than Casimero did.
C levels don't put on boxing clinics even against other C levels. They look C level at all times. Butler looked aces against Sultan.
Broner was a C level and he was putting on clinics against C level fighters like Molina ect. Butler is C level and Inoue will show that.
