Whether what angle you look, this is a good fight as no champion now who is willing to fight Manny. I don't think it's just about the money, maybe they still believe that Manny is hard to beat and that would tarnish their undefeated record. Well, Garcia is not anymore undefeated so he would take this fight, however, we cannot ascertain if this will happen since there's no official statement yet that it's already finalized.
Ryan Garcia is undefeated and so is Crawford and they are more than willing to fight Manny, it's not about the record it's more about the legacy, imagine being one of the guys who beat Manny and get him into retirement, Mikey is a perfect opponent for Pacquiao, I'm just afraid that he will imitate Marquez counter-punching style to beat Manny but let's see.
Two different set of fighters, although Marquez has laid down the blue print on how to beat Pacquiao, it took him a lot of fights before he figure Manny out. and Mikey is not a counter punching great, he loves to go toe to toe.
So I don't think that he will use this tactic or plan if ever this fight will push through. And I'm seeing that he will really go fight Manny and really test him in the early rounds, similar to what Thurman did. But it will be a costly mistake on Mikey (and just like the rest of the other fighters who think Manny is small and can't knock out/down them.)
