Aaron Rodgers indoors this season:
3 games. 72-of-102 (70.6 percent) for 1038 yards. (346 yards per game.) 7 TDs, 0 INTs. Averaged 10.2 yards per attempt. QB rating of 126.2.

There is just no fricken way anyone should dismiss how playing in a dome has had factored into Brees' historic season.
Would Brees adjust to playing outdoors? Sure. He actually played better outdoors than indoors in 2006.

But when we're talking about two historic seasons that are extremely close, one of them clearly came with a higher degree of difficulty. Rodgers TD percentage (of his total throws) was 9 percent. His average yards gained was 9.2 per pass. (Brees TD% was 7.0 and his yards gained per pass was 8.3.) Let Rodgers throw 155 more passes (which is how many more passes Brees threw while playing 70 percent of his games in a dome) and the projection for Rodgers is 6,049 yards and 59 touchdowns. And that is WITHOUT adjusting for indoor/outdoor splits. Rodgers played 80 percent of his games outdoors.
If someone wants to do the old school baseball thing and try to factor in leadership and various stuff that's completely not quantifiable, I'll absolutely listen to that argument. Because I do believe Drew Brees transformed that franchise. He probably did more to save it from leaving that city than any player in NFL history has done for his home team. (Of course, that happened several years ago, but we'll assume some residual carry over.) And unlike baseball, I do think leadership from a quarterback matters a lot more than leadership from a left fielder or a catcher. It's not a game where you can be a total recluse or a diva and ignore your teammates, but have an OPS of 1.422 and clearly still be the Most Valuable Player in the league.
But as far as statistics, when you factor in the environment, Rodgers easily had the better season.
