Without looking at it, I would suggest that they were on the field more than our defense because our offense controls the clock longer than Seattle's. That assists our defense because they face fewer drives than Seattle's defense does. This also explains why Dallas gives up more yards and points per drive than Seattle does but still averages the same points allowed per game average.
Question, game is on the line which defense would you rather have out there to make a game saving stop, Dallas or Seattle?
It is all pretty clear to me. I take Seattle as it was last year any day. Going forward? Dallas is on the rise. I like where it is going especially if they get a bruiser at DT in the draft and another safety. A couple upgrades here and there and Dallas will finally have a pretty good defense.
