Wow. So much that I disagree with here.
First off - Crawford has 20 HR/100 RBI power when hitting behind Ells and Pedey. He's a prime player to hit in the 3 hole. By putting him in the 3 hole, you extend your line up so well. Ells, Pedey, and Craw will be the top 3, and knowing how much Francona likes LRLRLR, I would say it will go Ells - Pedey - Craw. Why wouldn't you want to have 2 #2 hitters in Pedey and Crawford setting the table for Gonzo Youk and Ortiz? Not to mention the fact that with Crawford and/or Ells on base in front of those 3, pitchers are going to be using the slide step, which creates mistakes, especially hanging breaking balls because their legs get in front of their arm.
Crawford is a prime #3 hitter, but if you want to look at it as a Pedroia/Crawford as 2A and 2B, it's fine, whatever makes you comfortable with it, but I can almost guarantee you that Craw is in the 3 slot.
The other stuff - Drew hitting 3rd in your 2nd line up is atrocious. He'll be the 7th or 8th man in any line up. Having him hit before Ortiz in the first line up is just as bad.
Also, Scutaro will more than likely hit 9th with Salty in the 8th slot. Basically a 2nd lead off. I could see Salty splitting up Ortiz and Drew in the 7th slot with Drew in the 8th slot.
