Dayton's biggest problem is he can't make trades. he had the crown jewel of about the last 5 years in Zack, and he gets a shitty SS who hits exactly like Berroa & Neifi plus a decent (but totally one dimensional) CF who is always banged up. That's it.
Yeah, that's it. With in-house options that were free. So when he turns around and gets James Shields giving up a legit player in Wil Myers it only proves that he's a clown while Andrew Friedman isn't.
