Chacin is a talented pitcher...
He put up three 2 WAR seasons with the Rockies (in that crazy park)... one of those seasons was a 3.9 WAR.
Obviously he was hurt the last two years but was pitching pretty well for us despite one horrid start which inflated his numbers. I think it was short sighted to deal him so early.
Grilli - I'm fine with that deal as that seemed like a homage deal to put him on a contender... he was going to be released.
Keeping Chacin could have given us good innings and helped not start the clock on some of these young pitchers we're bringing up
