At least Butler will punch back, unlike a punching bag, hehehe. Paul might show his skills in this fight early, trying to evade those power punches from Inoue. But sooner or later he will be fold because he doesn't have answers to the Monster volume punching + power. This could be another great performance by Inoue and become the top 1 in the pound for pound list this year.
But Butler's punch-back surely can't be considered a threat. hehe. I also can't see him dodging most of Inoue's punch. I agree that he will turn into a punching bag by Inoue. Butler should be happy though for the opportunity to fight Inoue. I think he didn't expect to be in an undisputed match in the first place.
This will be Butler's most notable fight. If he will win, that's a considered jackpot for him.
For sure this is already a sweepstakes for Butler in terms of guaranteed money although Inoue could get the lionshare because he is the A-side of this fight. So no matter what will be the outcome, Butler is already a winner. Of course he wants to upset Inoue and create a inbalance in this division. But he will need a lot in this fight because no one has defeated Inoue so far. There is no written strategy, so very difficult task in front of him.
Inoue is heavily favored to win, but that doesn't mean that Butler doesn't have a chance. There is always a chance and opportunity for underdogs like Butler to win. They just have to make things work and grab that little sliver of opportunity when it presents to them. Who knows, maybe Butler can knock out Inoue in one of those rounds and we will all be shocked in disbelief
