Only 30% of his starts last year were with the Yankees. You might as well as assert that 2 below average months mean that a player can't be average for a whole season. Since you brought up RAA, Garcia is +18 for his career. You note that his 2015 was quite good at +24, but even taking that out, -6 runs over the other 144 starts is pretty much the definition of average. I really don't get your insistence on immediately throwing guys into the fire with virtually zero AAA experience (and not even elite prospects at that). Because Brad Radke did it for a 99 loss team 23 years ago? If Garcia is as bad as you say he is, he can easily be replaced by prospects during the course of a 1 year deal. If the prospects struggle, you may not have the luxury of finding a veteran replacement during the season exactly when you want, at exactly your desired price. Not to mention the risks of pushing the prospects, if you give them too many challenges at once, it is probably not good for their overall development -- you don't just push every promising 12 year old to med school like Doogie Howser. And of course the heightened injury risk -- Fernando Romero's performance was showing obvious signs of fatigue after about 110 IP last year, and this is a guy you want to skip AAA?
