Again, we've been over this before. The Cubs are clobbering a team in one game, then losing the next two by a close margin. It doesn't matter if you outscore your opponent over the course of a series if you score 80% of your runs in only one of the games. Sure, if the Cubs keep the same average but spread it out over all the games, then they'll start winning more. But that means they will have to become more consistent, which they aren't right now.
