Ya you're absolutely right. Lets Travis develop too, in case he isn't ready this year. No need to rush him in this scenario.
I still feel McCarthy is the exact type pitcher AA should be after, too. Pushes everyone down a spot on the depth chart (other than Stroman). Makes up for the hit they took with the Donaldson trade. Great peripherals, shouldn't cost a fortune. I don't ever feel confident predicting FA values, but a 3 year deal bridges the gap to guys like Norris, Hoffman, Osuna, Castro etc, while helping the staff this year.
