Did you even watch the Astros the last month and a half of the season? They were the best team in the NL and for a while, held the distinct advantage over the Cards. Also remember that Carpenter, their best pitcher, was unavailable, making it even more of a topsy-turvy series.
Yeah, coming back from 3-0 will do that for a series. Had they not made the incredible comeback, the other series would've been superior hands down. A classic all the way.
