There's reallly no bad result here. If they lose they are still getting rings and an NL pennant (as well as bragging rights over the Mets and Braves) and exceeded all expectation from any month this season (ok maybe there was that sweet spot in July when this seemed possible but even then I would have taken an NLCS loss, and didn't necessarily believe they'd even do that).
At the same time, they have blown a 1-0 lead and 2-1 lead, could have won this series at home, and didn't. The Astros are probably too deep to lose a coin flip game but it's still a coin flip, so, just get there. Hopefully both Wheeler and the bats will do better.
