No I know, I just don't think the two statements are interchangeable "Having an MVP" vs "Having an elite or great QB" are two very different things is all. I'm with you on if you don't have a QB that is minimum better than good, you're going to to need an elite Top 2 defense that is special to win a SB most likely.
Actually, I think having a great running game and defense is by far the most important ingredient in a great football team (obviously you need balance, you can't be too weak at any position, but the vast majority of great teams, including most super bowl winners, have had a great defense and running game). There have been many more super bowl winners with a great defense/running game vs. those with an elite QB/passing game and an average defense/running game.
This isn't necessarily an endorsement of trading Rodgers, nor sacrificing the future to keep Rodgers's/Adams to go "all in" now. (I honestly don't know what we should do, it's not an easy decision)
I just think it's too bad that we finally get a great defense along with a great running game at the end of the Rodgers/Adams era (since the last super bowl win).
