What I never saw him tackle was the dome factor. So I crushed a few simple numbers.
Per 16 games----and I included retractable roofs as indoors...though there had to be times the roofs were open...but still, it's kind of indoors...

Here are their career stats if the games played indoors and outdoors were revered. And remember...this would be all of Brady's indoor games were road games
But the stats reverse


Doesn't mean much except all of Mannings so-called "production" that is "better" than Brady's goes away, though I don't think there is that much of a difference, but Manning being in a dome would make up a lot, but Michael complains that Brady had better defenses...which he did, most of the time.
But I still contend stat matter, rings matter, awards matter, intangibles matter, testimonials matter. I perceive all of that edges towards Brady as the "GOAT" but Montana and Graham and Johnny U right there
