You hear it more and more each year, "the postseason is a crapshoot, blah, blah, blah" which I simply don't buy into that particular thinking. I think in most years the team best built for both the grueling 162 game season and for short series play comes out on top. You have to be built for both (one way to get there and the other way to finish the deal).
Records in MLB mean little as the regular season is nothing more than the longest qualifying round in sports. There are simply too many variables to consider such as scheduling (not balanced in this case), what division you are in, when you play teams, roster makeup/injuries, etc to decide alone who is the best team whether a team wins 86 games or 100 games.
Just qualify and then prove your worth as the best team in baseball in October.
I don't think is a crapshot outside of the one game WC playoff game (and some series trough playoff history), but you have to consider that Dodgers numbers are outliers and the game itself tend to get normalized when you have numbers like this. I would have more confidence in a team that have gone trough bad streaks, even if its a small one.
