Both have different styles and so I doubt that Brandon will mimic the style of Rey Vargas just to win. He has his own way or strategizing in this fight and fight Magsayo the way he knows it.
But for sure it will be his volume punching again, nothing will change a lot here, that's already what we call bread and butter, and that style has been working for him for many years except against Fulton who took all his best shots and received some as well.
Some versatile boxers can do the same strategy when they find their opponent is weak. In this case, Vargas had exposed Magsayo's weaknesses, so there is a possibility that the camp of Figueroa will implement the same strategy. It would be lucky for Magsayo if Figueroa will fight him toe-to-toe and do not take advantage of the reach advantage.
On the other hand, I believe Magsayo had studied Figueroa's fighting style and strategies, I hope his camp can find the weakness of the opponent and devise a plan to exploit it.
Might be, Vargas strategy though is to use his length against Magsayo by using a lot of jabs, and Brandon is not known to jab, he is a very definition of brawler, even in the first rounds of the fight against Fulton, he uses his aggressiveness and try to wear out Fulton. But Stephen was intelligent enough to grab him the moment he goes inside. So I'm seeing the same Figueroa in this fight, same strategy, he will try to wear you down with his volume punching. So it's the sheer volume of Figueroa. But to win against a volume puncher, Magsayo should be accurate enough, even if he has less output, if he is accurate then he has a good chance to win or maybe score a knock down in the later rounds.
