Here's a quick metaphor for those who don't have the mental capacity to understand basic market rate. Take a 1100 square foot, entry level home in downtown Los Angeles. You're going to pay $1,000,000 for it.
Is it worth that? Hell no! But you can gripe, moan, and complain all you want about it but that is the going rate in that market. The QB market is the California of all positions in the N.F.L. You can't compare it's market value to other positions. To change that, ALL owners would have to agree to stop paying over inflated contracts which would reset the market.
