I've maintained for a long time that the first team to realize that QBs are expendable will be the first true legacy team under the salary cap.
Keep a healthy, mobile, rookie contract QB under center, and build the rest of the team with the saved money. Every few years, go out and get another rookie, either through the draft or through trade. If you luck into a 3rd round Wilson, trade him for a king's ransom when his rookie contract is about to run out. Don't try to stretch for a franchise guy, just get a guy that is good enough.
I have yet to see a good organization try it, but I think it could be done successfully.
Franchise QBs are overrated UNLESS their primary goal is winning multiple Super Bowls, and they are willing to sacrifice the record setting contract. Obviously, a Brady, or a Rodgers, on a 15% of the cap contract is best, but that is even more rare than a true "franchise" guy in the draft.
