The #1 reason is that people always inflate and hype the player so that their 95th projectile projection seems like a 50/50 projection. I don’t mean the hype gets to their heads. I mean that the player was never that good to begin with or had much more to improve on, or that the improvement of something significant was assumed. Hot streaks are assumed always to be a new standard of play. Playing time granted because others were hurt was earned. Routine plays become great. Mistakes are forgiven. It’s a competitive labor market. Most players don’t pan out to the level we expect.
