I was sure that Shatkins found defence to be a market inefficiency, and you can get more WAR for less if the player plays defence first.
The problem they encountered was that they tried to turn their hitters into ''The Jays'' version of who they should be. They never coached to their strengths. Now, I guess, they have learned their lesson and are letting their hitters be themselves.
Scoring Runs and Preventing Runs should be equal in theory; you just need to acquire as much WAR as you can.
And maybe some power from Vlad. That would help.
