2017 Eagles are too low here I think. Top 5 in scoring. They were a really good defense and Brady and the offense made them look bad, which is even more impressive.
2007 Giants defense were good but not THAT good. Only 17th in scoring. They just executed a great game plan against us. I'd be tempted to put the 2001 Rams at the top.
I think the 2016 Falcons and 2011 Giants are definitely worse than the 2020 Chiefs defense. I'd put 2016 Falcons (27th in scoring, 28th in passing) at #8 and 2011 Giants (25th in scoring and 27th in passing vs an easy schedule) at #8 and #9 respectively.
2020 Chiefs are 10th in scoring and average vs run and pass. I don't think a Brady offense is a great matchup for them either. Then again they did shut down the Bills pretty easily. I'd probably put them at 8 in a top 10 list compared to the teams above and below them I guess.
