2020 cant get here soon enough
No. You are not getting it. The fluctuation is also caused by other factors. A jump in 30 points from one season to the next by Brady was directly attributable to the changes in the surrounding talent.
After his rookie year, Manning had only three seasons where his QB rating fluctuated significantly (2001, 2004 and 2013). In 2001 he had a slight increase in INTs and in 2004 and 2013 he had big years for TDs. All of the rest of the seasons his rating only fluctuated by
17 points and usually fewer than 10 points between two seasons. Why? Because the talent that surrounded him was remarkably consistent. While in his prime, Marvin Harrison only played fewer than 15 games once. Reggie Wayne played 11 consecutive years of 16 games per season. Edgerin James missed 16 games in 7 years. 10 of those were in 2001 (which just happens to coincide with the worst year for QB rating other than his rookie year.
In all of his seasons, the rest of Mannings stats were remarkably consistent. Yards, completion %, YPA all very consistent. Other than the blips mentioned above, even his TDs and INTs are very consistent. He also just happened to play 8 seasons with Dallas Clark, 11 seasons with Marvin Harrison, 12 seasons with Reggie Wayne, and 7 seasons with Edgerrin James.
And a whole new team. Just lucky I suppose. Lucked into a great team in Indy that coincidentally went to crap the year he was injured then coincidentally again lucked into a great Broncos team that was coincidentally bad just before he arrived. And I like how you cherry pick certain years to show he only fluctuated 17 points, meanwhile Tom Brady's average is 95.7, which is only 8.4 points from what he did in 2013.
I guess it shouldn't be a surprise that certain Dolphin fans would be so resistant to the idea that this stat might be meaningful seeing as only one Dolphin player ever posted a season with 100+ rating, and that happened 30 years ago.
