Thats a good point my friend, a team has to really evaluate how they can build a roster around a market value QB.
Obviously the million dollar question is..................who is the replacement if we dont sign our starting QB to a market rate deal?
And here is the problem, or even the fear every team must face in this situation.........what if the replacement is not as good?
You can very quickly go from winning 12 games a year to winning 5-6 games a year if your replacement ends up sucking.
There is no guarantee Lance is any good, that is the problem for Dallas. And you can say good, if he sucks we get a top 5 pick the following year and draft a new QB. But what if that top 5 QB is a bust? There is no guarantee that just because you draft a QB in the top 5 that he will become a franchise QB. There are lots and lots of example of top 5 QBs busting. So, then what? You sucked a year with Lance, now you suck a couple more years with a top 5 pick before you determined he busted, so we are looking at multiple seasons of 5-6 wins now?
You starting to see the problem with the idea of "not paying market". If you have a QB that is good enough to warrant a high-end contract, it is too risky to let him walk. I mean, what teams have let their franchise QBs hit unrestricted free agency that was not coming off a major injury (Brees and Cousins). I honestly cant remember the last time somebody like Dak was allowed to enter free agency, a QB in his prime that was literally runner up to being league MVP.
