Oh common, there's no need for silly post hoc explanations like this. Plenty of flawed hitters around the league have turned into useful pieces since the flyball revolution began, just because Smoak randomly happens to be one of them doesn't mean Atkins and Shapiro made their decision believing that Smoak would turn out to be a very good hitter. If that was the case then why did they stop at just Smoak, why not try to pick any of the other numerous hitters who have since seen their careers turned around in the flyball revolution. Or is the argument that every team that "found" hidden gems in flawed players also had "internal metrics" that showed that they would turn into good hitter?
You see how silly that sounds, I'm a big fan of Atkins and Shapiro, just because you like how they usually make decisions doesn't mean you have to defend every last one of them.
