Yes, Graham did. And that needs to be factored in. Graham probably pre-dates the modernization of the forward pass based on the film I've watched (and there's plenty available for those who want to make their own determination). Right around the time when the AFL comes into its own seems to coincide with the forward passing really starting to get where we see it today. Obviously not the same exact thing, the game is always evolving...but they weren't shotputting a watermelon like it looked like they were doing in 1940.
You make a good point about the 32-team era and how that acts as padding to regular season numbers as the dilution of talent is likely greater. Graham's performance in 1947 means that he was going against, likely, 7 best corners and safeties and rushers on a weekly basis. Meanwhile, there are times when Brady and Manning and Brees get to feast on guys like Trenton Robinson and Greg Toler. Though, we have to take into consideration how much those positions had evolved in Graham's day vs. other eras. I don't have that knowledge, I just know how QB and forward passing have evolved over time. Definitely worthy of further investigation, good point.
MVPs are tough because of the ballot. There's only first place votes, unlike in hockey. So it creates a really tightly-enclosed, binary scenario that doesn't lend itself to a lot of good. But let's evaluate a little further...
You call Brady the best ever and though you deride Peyton Manning in a borderline comical way, I think deep down you know he's way up there. So that's who Brees was going against for his MVP awards. Favre is going against who exactly? Young and...? Aikman? I mean, who else has a prime that lines up with Favre who is really that relevant...again, context matters. Brees didn't win any MVPs (he has a 2nd place finish for whatever that is worth) but that's like saying "well, Yzerman wasn't a First-Team All-Star in his career" ...well, yeah, there were a couple of guys if I remember, always getting in his way...
Moreover, and here's where you get tied in a knot. If MVPs buoy Favre above Brees (fine, acceptable) then MVPs carry weight...well, guess who has five of these things, three 2nd place finishes and a 3rd place finish? Peyton Manning. So he's got (disregarding single votes):
1st: 5x
2nd: 3x
3rd: 1x
Compared to Brady...
1st: 2x
2nd: 1x
3rd: 2x
This why the pick-and-choose where this logic applies vs. this logic doesn't apply doesn't hold weight when you look at the larger scope. "I want to count championships for Brady...but not Graham; I want to count MVPs for Favre...but not Manning..." it just falls to pieces. And I get that there's more to your (and any) argument than that. But it's about laying the logical, consistent foundation before you start building these list. They are built on ancient Indian burial ground quicksand the way they are worded...
Why do I think they're better? They played better, they are better against their peers (by a lot, in the case of Moon and Young), I'd imagine that Young as a better trophy case and award voting record...I doubt that Moon does, for various reasons. I'd just like to hear these things...there's an awful lot of guys that are in the "top 10 discussion" apparently, but it is a scatterbrained group. So I'm legitimately curious as to what we're using in these instances that propel Elway over Young...let's skip Roethlisberger, let's just go for the - what appears to be indefensible position - of Elway over Young. What is the case for that...there's a good chance we all learn something from this dialogue, if done right, myself included...
