He was the favorite ever since this fight was rumored, Butler was just hyped a bit because he will be fighting in his country, but if we look at their record and performance in their previous fights, it's easy to tell on who will dominate.
Casimero has the more powerful punches. He is also the one defending a belt. He is more aggressive. The odds are speaking of all these. Butler could put up a nice fight of course but it would be very dangerous for him to trade powerful blows with Casimero. He is not really a knockout fighter. He should instead try to run around and gain points to win this match. But he might turn a little more aggressive because he has the home court advantage. It will somehow give his performance a boost.
On the contrary, having the home court advantage, for sure he wanted to put a good show with his fans. So he won't run around and instead will try to go toe to toe with Casimero and hoping that he can score points and not getting knock out. And even if he lost this fight, at least he give his fans their money worth for buying his tickets. He is the underdog in this fight, he should fight aggressive, in my opinion.
We will see what Paul Butler's strategy is in confronting Casimero. But I doubt he doesn't know that his opponent is a strong puncher. He must have already carefully studied Casimero's abilities and punching power. His team must have already learned that of the last 10 fights of Casimero 7 was won by way of knockout. So I doubt that his home court advantage would push him to trade blows with Casimero toe to toe. He will have a game plan but not probably that one.
Cant really deny about Casimero punching power but there are fighters who are that able to tolerate or could withstand a particular level of power but lets see and Butler would able to
notice it out on earlier rounds.
