But the Braves are an extreme home/road team. They're only .500 on the road, but over .700 at home. You don't think that would translate into a different confidence level if they played a Game 7 at Turner Field rather than out in LA? How does something that's supposed to be a factor all year suddenly become irrelevant in October?
(I am not, by the way, arguing that "confidence" and "focus" and all that stuff aren't important; merely that it's much less of a factor than McCarver and his ilk make it out to be. Almost all ex-players radically underestimate how much random action there is in baseball, so they place far too much importance on the supposed mental state of the players. A guy goes 12 for 20 and it's because he's really confident. He goes 2 for 20 the next week and it's because he's lost focus. It's easy to see why as a player you sort of have to wrap yourself in that belief system, that you control everything, but it's not how the sport of baseball actually works.)
