This narrative of you can't be good unless you beat the best is wrong. They are the best teams for a reason, that doesn't mean the Reds can't be a good team. Besides, if the best teams only beat the good teams, do they get the same narrative?
#2 everyone in the central plays the Pirates the same amount of games, do you discount them for beating the Pirates also? They are the worst team in the division, you dang well better beat them, ALOT.
