It might be the mot idiotic article of the year except I've read it before. As Barnwell alludes to, this wasn't even his idea. He stole it from other people.
I first heard about it in the Peyton Manning era when people wouldn't stop crying about how much money he was making. Never mind that that he went to four Super Bowls after he got paid and not once on his rookie contract. Its built on the "system QB" fallacy and that escalating QB salaries are the reason good teams can't stay competitive. I have never believed that.
Certainly it's tougher to win with one player taking so much big money. But the real problem is that increasingly unproven QBs are being given huge contracts and they are not actually elite - you know, like SF did with Garapallo. To a lesser extent Osweiler a couple of years ago. While Rodgers is worth such a contract, Brees, etc - average QBs aren't, and teams are afraid to let them go. Until a team actually has a top notch QB, it might not be a bad idea to keep drafting and developing - not using firsts unless a true elite talent falls to you, like the Packers did with Rodgers, but use more than 7th rounders.
If you have a pipeline, and your starter is just average, it might make sense to trade him if the offer is right. But if you have a good or better QB, trading him away is usually asinine unless you have an in-house replacement you think is as good or better.
