Currently Casimero 31-4-0, 21 KO while Butler 33-2-0, 15 KO. Actually if you look at the statistics they are both quite strong and indeed have great potential but if you look further in fact this is clearly in Casimero's favor and it's not wrong that Casimero is the favorite to win this fight.
actually butler is a good boxer and let's not forget about him being a world champion but butler has a problem with his punches he throws too many punches which is pointless in my opinion and this is definitely going to be taken advantage of by casimero
He might get tired if his style will not work against Casimero.
Casimero is a great counter puncher, he has a deadly punch that would hurt and KO an opponent if not careful in the ring.
Look at what happened in the fight against Tete, Casimero was just waiting for the right timing to counter Tete and his plan succeeded and that punch changes the fight and he won by KO, it's an upset since Tete was the favorite.
Fan fact, Tete beet Butler, so most likely Casimero would also beat Butler.
This is something that Casimero does have. He always manages to make something unexpected and even he is quite deft in intimidating his opponent.
With the weakness of Butler who often throws punches, I think this will be used because when that happens Butler's defense will be a little weaker and this must be used well by Casimero.
I think the aggressiveness of these two boxers will present something different in this match, now it depends on how their stamina and strategy are. If Butler will apply the strategy as before by wasting punches then it is certain that Casimero will win this match
