Yes. Correct.
Browns GM lost his job after that, and many people admonished the Bills for paying an old Von that much money when older players get injured more often.
By your definition of a GM, we could simply fire the GM and scouting staff and simply select draft picks based on the average consensus of prognosticators.
And really we should never fire a GM, because they can’t possibly know what the right decision is… we should still have Buddy Nix.
