Well, that's a given. I would say Minor is the most likely to be traded because he is the most likely to get the best value for the Braves relative to his worth. Beachy's lack of track record makes it unlikely that they could get someone that is as valueable as Beachy. Same goes for Jurrjens...
The problem is he has been so consistently good from day one, that there was no real jump in his prices.
Also, Tommy Hanson is absolutely horrible holding runners on.
