Plus-minus tends to be very noisy data; it’s hard to separate an individual from a group performance (this is actually what adjusted plus minus systems like ESPN’s real plus minus attempts to do.)
But there are players who clearly outperform the what you would expect and what should statistically be within reason. Which makes you re-evaluate what you know about a player and think again about their value.
Sometimes it’s more a function of who you are being replaced by than what you are actually doing, but there are players who year after year find themselves with surprisingly high plus minus rate.
What I’ve attempted to do is to find truth in the data and search for “underrated” players(though I hate that term, for 80 percent of the league fit and situation is everything).
Here are some of the guys who came out of those findings.
