Plus minus is a rort
Single game plus minus isn't always a great indicator of how an individual has performed but building up +/- data over several games does. Advanced stats are helping analyse players like never before and uncovering things well beyond the raw number. Embrace it or get left behind

While I agree +/- in one game is not helpful, over a season it can be quite a telling stat.
You only have to fish out Michael Beasley's +/- his last season in Phoenix, to see that over the course of a season, it shows why he dropped out of the rotation, and eventually was amnestied/bought out.

"The is why the nerds will have us believe they can coach NBA teams and that current coaches are obsolete."
They would be wrong. That doesn't mean the "nerds" are obsolete.

"I 100% agree with you. People use it to show how good an individual player is, but your +/- score is evenly affected by everyone else on the court. In reality, you have 1/10th influence over your own individual +/-"
That's not entirely true. It's difficult to succinctly explain, but essentially: having an influential player on the floor (or off for that matter) potentially impacts the game dynamic more than the '1/10th' you quoted because the performance of one player is dependent on virtually every significant variable imaginable.
In saying this, I know what you're getting at and it's worthwhile point to make. Hence looking at a single game +/- isn't particularly useful, especially without the proper context.
"For some reason, these forums love the +/-.. its the only place I ever see it refered to."
Long-term adjusted +/- scores are useful descriptive statistics. Isaac linked an ESPN article which illustrates how widespread the general concept has become.

Well said, Isaac.
