The Donaldson trade was an outlier. He wasn't going to make those types of trades consistently, if ever again (Beane had one of the biggest brainfarts in recent memory). In that case, you have to look at the things he's more likely to do on a consistent basis, and that's where you evaluate his ability to develop talent, to give players the best chance to succeed, to factor in service time/options for the betterment of the team long-term, to acquire talent in general (does he look at WAR now, framing, defense, etc), and so on. Unless he had a trade lined up for Mike Trout or something (equivalent of Donaldson trade), he's not a guy I'd want to have around to build on 2015 and help them bridge to 2017-beyond in the best way possible. Shapiro/Atkins at least have the right mindset.
