Right because teams with bad offenses never seem to lose. Look it's pretty simple, and the previous poster explained it well. There are three phases of the game. To win rings you generally need to be good at all 3, especially offense and defense. And typically you have to be great in one and good in another. Great in one and bad in one can win lots of games, but will also lose at least a few a season. Those teams don't get rings. Would you rather have a ring or not?
