That may be true about the players, but whether I'm worrying about the Brewers or not has no impact on what the Cubs do on the field. While it is true in sports that teams need to be focused on what they can control, we as fans don't need nor have such restrictions. My worrying about what other teams do has no effect on the Cubs, so if we wish to discuss the Brewers or any other team in regards to this season, it has merit.
