First of all, there were 21 other starters on the team, not to mention great coaches and special teams players, that brought 3 rings to the Patriots in 4 years. Look at the Patriots now. Players are hurt, coaches have left, and the Patriots are not a very good team anymore, even with Brady.
Secondly, if Quinn left, he's a top 5 pick probably. We're picking 13 right now. I think we'd need more than a 1st and a 4th to get him. If the game was called, "Quarterback," I'd be all for it. This is football. We need a decent number of hits on draft day to get our team back.
Again, a great QB doesn't mean the team will be great. To make my point, Dan Marino never did win a superbowl, and in my opinion, he's the greatest QB ever.
Finally, I admit the most important thing to rebuild our franchise is to get a great QB. I'm just saying there other ways to do it than to bankrupt our bank of draft picks.
