Kahnle mostly netted them Rutherford, not Robertson. It was obviously some aggregate of Robertson, Kahnle, Frazier but the vast majority of the value was in the young controllable fireballer.
I'd make that trade too, but the chances of getting a > Top 50 guy for Colome are sliiiiiiiiiiiiiiiiiiim so I'd rather hang on to him for next year than trade him just to trade him.
