First 6 seasons (as a starter, so no 2000 for Brady or 2017 for Mahomes):
Mahomes: 66.5%, 28,140 yds, 7.9 y/a, 219 td, 62 int, 103.7 rating, 3 SB titles, 5 AFCCG, 2 MVP, 3 SB MVP, 3x top 5 MVP
Brady: 61.9%, 21,558 yds, 7.0 y/a, 147 td, 78 int, 88.4 rating, 3 SB titles, 4 AFCCG, 0 MVP, 2 SB MVP, 2x top 5 MVP
So ok, great start for Mahomes - even better than Brady, even adjusting for the era in which they played.
But then Brady hit another gear entirely.
Next 10 seasons for Brady (technically 11, but 2008 he missed after getting injured in the first Q of the first game):
65.0%, 44,595 yds, 7.8 y/a, 341 td, 82 int, 102.5 rating, 2 SB titles, 8 AFCCG, 3 MVP, 2 SB MVP, 7x top 5 MVP
And then after that, he only did this to close out his career - last 5 seasons (ages 41-45, mind you):
65.5%, 23,055 yds, 7.1 y/a, 161 td, 52 int, 96.1 rating, 2 SB titles, 2 conf championship games, 1 SB MVP, 1x top 5 MVP
So I want to see if Mahomes can reach a new gear like Brady did. I want to see if Mahomes' next 10 seasons can be what Brady's next 10 seasons were following these opening six as a starter.
