I think that mattered less. LF was doable between Holt, Young, Hill and Shaw and Ramirez (just wanted to see if you were reading the last one). If Benintendi were expected to have Christian Vasquez' bat, the position of need would be staffed another way.
Playing LF at Fenway itself is something which stands outside of being a good outfielder. Carl Crawford is a primo example here. Only way to do it is to do it.
