His point was, we traded Peralta for Sproat and Jett. Now we traded Frias and Ragsdale for May (and JoJo).
May basically replaces Freddy. What did we actually gain? We lost Frias and Ragsdale for essentially nothing, and had we just kept Freddy, we would still have Frias and Ragsdale, and be in the same basic position.
I don't think Freddy would have cratered like he did if he had stayed with the Brewers. I think we would have seen the same basic Freddy we always had seen.
So in a nutshell, would you rather have good ole' Freddy, Frias and Ragsdale, or would you rather have May, JoJo, Sproat and Jett?
To be honest, I'd rather have Freddy, Frias and Ragsdale.
