If you are going to make such a strong statement, you should at least attempt to back it up. For every example of when it worked you may wish to sight, I can give you an example where it didn't, so anecdotal evidence isn't going to sway me. The fact is, there are any number of ways you could try to quantify who the winners and losers were, so I don't thin it's possible to make such a declarative statement either way. Economics 101 suggests it has to be pretty close to even, the way I see it. Also, Greinke had the 5th best ZiPS projected ERA among NL starters for 2012 and currently sits with a 3.13 ERA. I don't think he's anything but a very solid ace at this point.
