Anyway back to the fight, I would still support and believe in him that he can avenge his loss this time around. He just made some mistake and Martinez in his first title fight managed to upset the champion. Just like Ugas vs Pacquiao back at the day because the latter expected to fight Spence Jr.
While on the other hand, Martinez knows already how to play with Ancajas. Not unless the latter has some new moves and strategies to bring out the fight.
For sure, Martinez is just doing some work on how he will improve his last strategy used to defeat Ancajas. He is more of a not too pressured fighter at their training since he does not even feel the struggle in the first match. On the side of Ancajas, the adjustment really need to be big, and coming from a loss, that might make him more pressured to win as he will always remember how Martinez dominates him at most of the rounds on their first meetup.
That is something that Ancajas needs to forget and just focused on the current challenge.
Yes, both will adjust for sure, just because you fight a boxer you will know his style in the second fight. What if Martinez suddenly switch stance, can Jerwin train for that?
That's why we see boxers who can really readjust their game plan after reading their opponents. But this boxers are the elite one, Floyd or Terrence Crawford, they have boxing IQ that is not being taught in the gym. Hopefully if Ancajas focus and has the ability to make adjustments, then his chances to win might increased.
