I also think the defense and special teams is getting lost in this complimentary football discussion.
When you have a lead, part of complimentary football is the defense getting stops or at very least making the opposing offense use a lot of time to score.
Special teams is part of complimentary football because if you do get in a situation where you gotta punt, the punter can pin the opposing team deep. Or the field goal kicker makes a clutch kick to extend the lead, etc.
Complimentary football is not just the offenses job.
