When you have a new QB and happen to win a SB shortly after his arrival, you trade him for as many picks as possible and start all over again, drafting a QB in the 1st round until you hit. Instead of paying millions of dollars on the QB, start paying to keep a strong defense and the players needed to keep a fresh QB upright. No more of this QB trying to control everything and paying out so much cash you can't keep the players you need.
Why? Just using the Farve, Rodgers scenerio. 2 SB's with BF, and 1 with AR. Why keep them if you aren't getting there?
Building a strong defense and keeping it together is FAR harder than building a winning team around an elite QB. Having that extra cap space is great for signing free agents but how many elite pass rushers or coverage guys are making it to free agency each year? Re-signing your own guys hasn't seemed to be an issue for the Packers cap-wise with an expensive QB so the only real issue it seems is signing free agents. I'd rather have an elite QB than be able to go out and sign two extra free agents who the team is going to overpay because free agency is ALWAYS more expensive than re-signing your own guys.
When you have an elite QB I think defensive coaches matter more than offense because, as I've said before, that elite QB raises the level of play of everyone else on offense but there's no position that does something similar on defense. Therefore coaching a great defense and covering up holes is going to be naturally harder on defense. Especially since what seems to determine success in the NFL isn't necessarily the number of strengths on the team but the number of weaknesses. Great QB play can cover a lot of weaknesses on offense but, as we saw against the Bucs, once a team finds that weakness on defense it becomes a major hurdle to correct.
