That fact alone will be one of the reasons why Ancajas should be more eager to get the belt that was once safe in his possession before he got lost by a first time title challenger, Martinez. Let's just give Ancajas the benefit of the doubt too because having a sudden exchange of opponent will of course make him struggle or any boxer in the industry as Ancajas himself didn't prepared for Martinez.
Definitely, it is an anti-tempo where an opponent has to be changed at the last minute. Since the boxer needs to scout, prepare a strategy, and put it in the boxer thru training. The last-minute change of opponent is disastrous to a boxer since he needs to throw away all the initial preparation and input another strategy at the last minute. Somehow a boxer is accustomed to the initial training regime and has trouble adapting the new strategy to the new opponent. That may serve as an excuse in the last fight, but it won't be this rematch.
So I think we will be seeing better Ancajas this time and I hope he can pass the weight limit requirement without any problem.
