You just can't expect this to happen season after season. We waited for the Cardinals to "come back down to earth" last year, it didn't happen until the World Series. Houston is playing good baseball, they're getting great pitching, some timely hitting and executing fundamental baseball. Why would anyone expect that to stop? Plus they have the experience of last season when they went on a run to come within a game of the World Series. The Cubs, as presently constructed, are not capable of stringing together a long winning streak or two to make a serious run at the WC.
