Yes, my examples talked about players who are having great seasons but the same principle is true for players who are having mediocre or even bad seasons
I'm not at all sure where the WAR line is between good, mediocre, and bad players are but I think it's safe to say say that there are more mediocre players than good or "bad" ones. WAR doesn't define which of those mediocre players are better or worse than others in that group because due to that 17% thing they're all statistically the same. Yet we've become so dependent on WAR that we tend to think of a player with a WAR of 3.5 to be a better player than someone with a WAR of 2.5 when, even according to Fangraphs, there's no evidence to support that.
Look, I didn't title this thread and that title doesn't reflect my beliefs. I think WAR is useful. It's just not as useful as most people think it is.
