Well, then if we know the Cubs will win at least one, 1 run game this season, assuming their run differential doesn't get worse, we've predicted that the Cubs will improve their winning % to some degree. Great work everyone, that's a wrap! What if the Cubs don't play any one run games from here on out? That is possible to although very improbable. Just pointing out flaws in your theory since we don't know how many one run games they will be in.
