The Dodgers show, imo, one of the issues with "efficiency"..... Sure, they have more / better prospects since they didn't trade for Dozier, and spent less, but to what end, exactly? What could have been last year, or how would this year already be different, if they had acquired Dozier instead. IMO, it shows how efficiency should not be THE measure of every decision for a MLB team. It's not like they are short of resources....but they are of 2B.
