Not all franchise QBs played their first year, yet the team didn't decide since they hadn't seen them play they needed to go out and keep blowing draft picks on QBs. So there must be some way that teams use to decide if a player is developing for the future outside of playing them...
most QBs, esp. recently, have been guys that get started in their first year. it's done because thats the best way. only way to really find out if he is ready to start is by letting him start. there is no other way.
Obviously if you sign a young FA or draft a QB you expect them to be able to grow into the starter, but you need to have a secondary plan in case THIS YEAR they are unable to do what you want.
why wouldn't the secondary plan be another young QB who, although they might be a long shot, still has the potential to be the long term guy?
The problem with your logic is that no matter how you handle your future franchise quaterback's first few years, it's a risk and you may need to move on to another prospect. Whether you play them two years or they can't win their job in the first two years, if they haven't done poo in their third year you HAVE to consider moving on either way.
not a fail free plan for sure, but still better and a much quicker way of finding your franchise QB than the stop gap way.
What you seem to be missing is the idea of competition in camp. The "Volek Figure" is there effectively as a fallback; if the others can't improve you know by his time in the league (and in our coaches cases working with him in the past) what he should be capable of providing. Competition is there to elevate all of those participating. It may just be your youngest guy comes to the top, perhaps not in his first year but perhaps in his second or third; but it may be you need to bring in new competition at the position.
what you see as a fallback is what i see as a crutch.
competition should be for the long term job.... not just this year. you get the team no closer to finding the long term answer than you were before by going after an old guy.
going after an old guy is a path that john fox would have taken because he didn't trust the youth. we should have kept him around if we were going to address the QB situation the same way.
it's time to start thinking outside the fox shaped box and start getting aggressive about finding the franchise QB.
