Even though passing is inflated and bonkers now, I think Brady probably keeps these records for a few reasons.
1. Most of these mobile QB's likely won't have an extremely long 20 year shelf life given playing style.
2. Also, given current salaries, most of them are going to be way too rich to be having 350 pound HGH mutants running at them when they are in their late 30's.
If I'm wrong, feel free to bump in 2042
