Hey if we are going to talk stats in the NBA thread I think we need to lay down some law so people don't just spout bullshit. Like:
- Individual defensive metrics are pretty worthless, especially when you're talking about what someone's doing in bench player minutes.
- Individual offensive metrics are only marginally better. Interaction effects make statistics based on stat-sheet numbers (points, rebounds, assists, etc.) somewhat misleading. However...
- +/- stats, even though they capture everything, have so much noise that they don't really become meaningful until a player's career is basically finished.
- More often than not, a player's MPG (basically, how much a coach wants them out on the floor) correlates more strongly with their winning percentage than whatever the advanced stat someone is citing is. Seriously. It's a better predictor than Hollinger's fucking PER, so stop bringing that shitty statistic into serious discussions.
- Team stats (pace, offensive/defensive rating, etc.) are pretty reliable, but they are dependent on coach and lineup and can be dramatically affected by individual absences due to injury.
- Three point shooting is like batting average, what someone shoots in one month tells you jack and shit about their true talent level.
Basketball isn't baseball. Advanced stats can tell us some things are overvalued and undervalued but most of it is pretty common-sense if you stop to think about it for a minute. Basketball players have a ton of possessions per game and unless they're rookies or having their stats in/deflated by a weird system, you can usually figure out about how good they are within 10-15 games. If a stat tells you someone's an insanely great defensive player but you know they aren't from watching the games (Memo), you might as well go with your gut.
