So if you play a weak schedule with a high ratio, doesn't that somewhat distort any true evaluation of the strength of a defense for the purposes of predicting future outcomes? I understand the concept, but if you have a "bend but don't break" D against weak offenses, you can't expect that to factor into any predictions of future opponents of higher quality. It's an interesting statistic, but I'd have to see some results over time that support it being a good measure for rating how good a defense actually is. I'm not disputing it, because you do an amazing job with stats...I just see some holes in this one.
