I think the Jays OBVIOUSLY would have preferred to switch Bo and Gimenez from day 1 and the only reason they did not was that they didn't want to disgruntle their star. Which is fine logic, honestly.
Positional adjustment theory would tell you that moving a player from one spot to another is assumed neutral for overall value. So swapping Bo and Gimenez would not change their individual production or the team's WAR. But it's so complicated and the assumptions fail at some point, otherwise it would not matter where anybody plays, at all.
