I don't buy the dome argument as much as it's just the era these guys play in. Hasn't slowed down Rivers, Rodgers, Roethlisberg, Manning (The other one) are all inside the top 10 all-time TDs. Ryan and Stafford are top 20. It's been a pass-happy league for a little while now, and it shows based on where the guys that have played for a long-time are on the list.
My original eye roll was aimed at the idea that Brees only got where he is numbers-wise because of the dome/division. Other guys had similar advantages but didn't take advantage as much as Drew did. Sure, it didn't hurt, but he has earned where's he's gotten with his abilities. To suggest otherwise, that it's simply a matter of circumstances is ;laughable.
