Like I said earlier today. If the Cubs play .500 ball the rest of the year, the Giants would have to go 27-10 AND the Dodgers would have to go 25-13 for the Cubs to not make the playoffs. So unless you are concerned that the Cubs are going to absolutely collapse or both the Giants and Dodgers are going to get ridiculously hot (don't forget the teams still have several games against each other so each one is a loss for one of them), it's not yet a concern
