I'm just using your own words...and I do think there is a big difference between calling someone elite or saying that he is not one of the greatest qbs playing of his time. Two rings, and having two of the greatest postseason runs in our franchises history in my eyes qualify Eli being called one of the greats of his time.
Anyone putting Rodgers into this discussion is just reacting on the last game played. He wasn't a starting QB until 2008 and he just doesn't have the total resume to make a comparison like that yet. Granted, if he continues on the way he has been he will definitely eclipse most (if not all) of the players mentioned, but let's wait until he gets there first. Lots of QBs over the course of history have fallen into that category.
Peyton: I've always liked clutch QBs over stat guys (one of the reasons I think Montana is a better QB than Marino, stats aside). Peyton very much reminds me of Dan Marino and has been more successful. However, if given the option for a big game, I take Eli every time (just like I'd take Montana over Marino every time except maybe in a QB competition).
Brees: This is a bit tougher. Better stats but half the rings. I like Brees better than Peyton or Rodgers (resume wise), however his one ring was more due to a pick-6 then his own heroics (which is not to say he didn't play very well in that Super Bowl mind you). I think you could make a very good argument for Brees being better than Eli, but given Eli's heroic wins, again I favor the clutch performer. That and I'll readily admit that I'm being a homer here.
Roflberger: He suffers a bit from the same problem that Eli does ... he doesn't look like a prototypical QB when he's doing his thing and he doesn't have the outrageous stats that someone not familiar with how he plays would ogle over. However Ben (as is being shown now) is a winner and sometimes wins and rings are the biggest stats there are. In this regard, Roflberger is definitely in the Top 3 in the league.
As for your "takes more than a QB to win a SB ...", don't be a straw man. You as well as I know that the QB is the single most influential component to a SB winning team (especially in the current climate of the NFL).
Having said all that, all the QBs mentioned are today's top QBs (no matter what order you want to put them in) and the fact that we can have this conversation is a testament to the fact that Eli, is indeed ... elite.
