You stole my only answer with Aikman...
But Young? Sure, he was always in Montana's shadow, but the guy was really good. He's still the highest career rated QB in history.
There is a trend with elite QBs lately. They tend to win their first Super Bowl with a REALLY good team, and they are just the game managers. As time goes on, they have more and more years in the system and get better and better at making their offense work. GMs can't keep complete teams forever, so it slowly degrades and becomes that once average QB's show, because he's the only consistent leader. I wonder if we can do this? Fitz just keeps working Gailey's system, while our team is built to be better and better. Then when we're healthy it all comes together and we win one as a team, and maybe, just maybe, then our core players (including Fitz) can continue to carry us for awhile. Just a thought, of course.
