Seattle was simply left out for convenience. Baseball would have an open revolt at such a nauseatingly cynical system. In football, offsides is five yards, holding is ten yards, a personal is fifteen yards. Nobody really knows what pass interference is. Part judgment, part acting, mostly accident.
Baseball has no penalties at all.
A home run is a home run. In football, on a score, you look for flags. Football acts can all be repealed. Baseball acts stand forever. Just when we thought there couldn't be anything worse than penalties, we get instant replays of penalties.
