Manny's cutman co-working a corner with Floyd Sr.

This past Friday, I saw something that instantly got my attention. I saw trainer/cutman Miguel Diaz, co-working the corner of Mickey Bey. Micky Bey is trained by Floyd Mayweather Sr. Everyone's clear on the fact that Diaz is in fact the cutman for one Manny Pacquiao. He also has a few charges of his own. One such charge goes by the name Marcos Maidana. In December of last year, Diaz found himself on the opposite side of the ring, working the Maidana corner. When the fight was over, the trainer/cutman vocally stated that Alex Ariza is a cheater. Why would someone that works corners with Ariza accuse him of cheating? Do you think that Miguel Diaz has some kind of knowledge of the kind of cheating he accused Ariza of? Do you also think that The Mayweathers have been warned or informed about the shady practice used by Ariza? These men seem to say with great certianty that Manny Pacquiao has dabbled in the sauce. Do you think inside information have caused the rift over drug testing? It just struck me as odd to see the 2 working together. I'd have to assume that big Floyd had to ask Mr. Diaz why he accused Ariza of being a cheater after the Khan-Maidana fight had concluded. I'm not in any way trying to imply anything here (lord knows I don't want the full brunt of Pacquiao's legal team to come down on me), I just found it odd, and I'd like to get you guy's opinion on the matter. I know there is a substantial backing for both fighters so I'd like to get people's takes on the matter.
