Duffy was impressive as crap before TJ last year. Paulino was even better. They'll be back to normal (or should be given the recovery rate of TJ surgeries these days) by the end of this season/offseason. Zimmer is flying through the system impressively.. They were always going to resign Guthrie.. They may have still gone after Santana.. They didn't need to give up a potential star, and 18 years of control of other good prospects for 2 years of an ace when this team, ace or no ace, needs a sizable miracle to even make the playoffs.
In a two years, when hosmer and co. are hitting their stride - YES. Do it. make a trade. but now? no. it was a panic move when we didn't need to panic.
