The NFL jokingly stands for “Not for long,” but that isn’t the case for every player.
Many NFL players, and particularly those on roster bubble, see their careers last fewer than five years. While Pro Bowlers and high draft-picks tend to last longer, it’s still common for their careers to wind down by the time they hit 30, when they typically begin exiting their prime if they haven’t already. There are, however, a number of players have defied age and continued playing into their 40s, earning them both longevity points and “unc” status.
