I don't know how you put Manning over Brees.
Manning had the better WRs, RBs and a great O-Line
Brees lead the league in yards 7 times, TDs 4 times, Compl % 5 times.
vs Manning 3 times on yards, 3 times on TDs and twice on compl %
And Brees can make all the throws Manning can make
I rank Peyton higher on the basis of his being able to not only translate across systems (Mora --> Dungy / Caldwell --> Fox --> Kubiak) but really create his own system and only be slowed down by the GOAT strategic genius of Bill Belichick. As silly as it may sound, I think it's important. I also think that, frankly, Tom Brady
Also, sex appeal.
He's the qb, so of course he gets the blame. My view is the Packers have built poor teams to support Rodgers. And yes, I watch Packers games too.
The poverty of roster talent is overrated. They've had the best pass blocking line in football, a quality running back, and a quality wide receiver pretty much every year since 2013. They've also had considerable talent/investment in the defense, with having Clay Matthews, Julius Peppers, Mike Daniels, Sam Shields, Morgan Burnett, and Kenny Clark.
For the defense, it's been coaching.
The Davante point is head-scratching. Did you watch the games? He torched top corners, including Peterson. You can't put up nearly 1,400 yards when you can't separate (and play the bears and vikings twice).
LOL!
Davante does not torch people. He gets some separation at the base of his route with his elite footwork and foot speed off the line, but good corners close the separation quickly because he lacks speed. This results in him having an extremely high contested catch rate, low yards per reception (despite having the most prolific deep passer in the league), and very low yards per target.
For reference on yards per target in 2018:
Julio Jones - 9.9
Deandre Hopkins - 9.6
Michael Thomas - 9.6
AJ Green - 9.0
JuJu Smith-Schuster - 8.6
Davante Adams - 7.4
(For reference, Jordy Nelson's career Y/T was 9.3)
If you watch his highlights, you'll see that nearly all of Davante's catches past the line of scrimmage gain no YAC because they are in contested single coverage. That's because he can't separate.
