How did we get so far down this 4,000-yd rabbit trail? Those stats don't necessarily translate into championships. As an example, Peyton Manning has the most 4,000+ seasons of any QB in history, 12.
Yet having a dozen 4,000-yd seasons has only netted him ONE RING. And goodness knows he had weapons around him.
On the other hand, both Joe Montana and Terry Bradshaw have four rings apiece and yet NEITHER of them is a member of this 4,000-yd passing club (at least according to the site eriadoc pointed us to). You know what the DID have? Pretty damned good supporting casts around them and pretty damned good defenses for when they had off days.
I think we have a pretty damned good defense. However, we could add a couple more pieces to a pretty decent supporting cast.
I'm of the same mindset as TPN (or TexasMike or whoever); you gotta have a good TEAM to win it all. Having a 4,000-yd QB means squat if you don't.
