In response to nhsteven's comment:
Bad 1st innings often render a team out of the game.
It does have an impact for sure, but does a team really have less of a chance of winning if a pitcher let's up 4 runs in the first then shuts out the team for 5 innings (4 ERs in 6IP for an ERA or 6.00) or lets up 4 in the 6th after a shutout for 5 innings (4 Ers in 6IP and a 6.00 ERA)?
I think the 1st case is worse, because the team is much more likely to be behind 4; once you play behind, like other sports and in life in general, it's harder; you can't steal, you get impatient at the plate, you burn out your bull pen, the opposing pitcher is more aggressive/comfortable, and so on. Case in point: The 2012 Red Sox. And. this particular facet of the team for the most part cannot be blamed on BV.
