re: 2011 Defense vs 2019 Offense, Who you got?

This is really an unfair question. It would depend on the other side of the ball.
The '11 defense would win the battle for one maybe two quarters, but would the '11 offense be able to keep the defense off the field long enough to rest?
And vice versa. If the '19 defensive gave up long, time consuming drives, would the '19 offense be on the field enough?
So, '19 team was better overall, but I would take the '11 defensive if all things were equal.
