This move is about OF range, not OF arm.
McCutchen's range is among the worst in baseball in CF... so moving him to right makes sense, since 81 games will be played in a small right field.
You definitely NORMALLY want your weakest OF arm in LF, but the range impact is more important than the arm impact statistically. So you set up your OF to be optimal for range over arm strength.
Marte in CF and Polanco in LF makes sense at PNC Park. McCutchen, unfortunately, has become the outfielder that Pittsburgh must "hide" defensively.... and at PNC Park, that means RF.
