I would beg to differ a bit. Agreed league has become a passing one, passing game dictates more Points and more pizzazz. But to counter your argument , a good running game makes the QBs life easier ,and opens up the passing game. As Mahomes found out in the last super bowl, with all the offensive power they had they couldn't put up points at will.
I agree - QB , pass rusher and OT ( blind side ) are premium positions.
corner is not such a premium, since there is no “shutdown corner” in NFL anymore . Even with current players like Ramsey, Sherman, Petersen are better ones but they cant shutdown the receivers all game . Routinely teams find good corners in rounds 2-4.
linebacker is more read and react position by design. MLB need to read the offensive formation and adjust the defense what to expect , so he becomes a QB for defense . Luke , Bobby are generational talent who could excel at recognition and fill holes, cover TEs, tackle surely . I think its key for any dominating defense to have one good MLB. Ray Lewis for Baltimore defense . Now Devin White for the buccaneers defense.
so you put a value on that !
