few seasons. He doesn’t look all that different from the younger version of himself. His ball velocity has dropped considerably, he can’t make the same throws that he used to, and he’s probably the slowest person (right now) ever to play at any position in the NFL.
Bonds was SMASHING all-time records in his late 30s and doubling his HR pace above that of his first 10-12 seasons.
Brady’s super power is longevity or slowing his decline. Dozens of QBs have had season much better than what he’s done in the last few years. He might *also* be cheating, but it’s hardly comparable to Bonds.
