I think there's a simple reason why the Red Sox are going to pull down the Yanks from behind, even trailing by 3.5 games, and win the division:

False hope.

Think: finally slaying the Yankees in the regular season, and coming from behind to do it, is the only way to top last season for giving Sox fans false hope of finally winning it all.

Then they lose to the Wild Card Yankees in the ALCS.

You heard it here first.
