Paul Butler is currently (+100) to win the bout outright, while you can get (+100) on John Riel Casimero if you fancy the incredible upset.
I'm not sure if the odds are reliable because AFAIK, Casimero is the champion and the better fighter, with +100 for Butler, then most likely the odds for Casimero is very attractive.
Although that a highly anticipated fight in December, still if the fight are made outside of the US, there are fights that are going to watch and bet for this fight.
And being the favourite, I think Casimero will have be bigger change to win, after all he is the champion and has the experience and the tools to beat a fighter like Butler. Of course, not belittling Butler, he might be a good boxer, but Casimero has power in both hands and I'm seeing that Casimero will land his patented right hand and will put Butler to sleep.
And then we speculate on the Casimero vs Inoue as we are salivating on that fight for a long time now ever since it come out prior to this fight.
If possible, he should do that. It will bring more noise to call in for Inoue's as his next opponent.
Money will talk once fans already call for this event to happen, he need to create more noise in his name internationally, from that it will be unavoidable
for these two champs to meet inside the ring as soon as possible.
Regarding to this fight against Butler, he needs to be more serious and active to make sure that the impact after this fight will
Bring more exposures to his career. Not just those trash talks, but the way he wins is very important to his name.
