The post I was responding to was asking where to place Pedroia under the assumption that he would return to hitting like he used to, in which case 3rd is a very logical spot to put him in. That said, when it comes to batting order, OBP is king. Pedroia's .369 OBP would have been one of the best on the team last year, in which case 3rd is still a very logical spot to put him in.
As an aside, I really like keeping JBJ in the 9 hole.
Also, it bears repeating that batting order doesn't matter that much, so I'll be happy with what Cora decides.
