CP3 ends his career with the 3rd highest adjusted on-off across the last 3 decades. One of the most impactful players of all time
Some people cite on-off for a series of games, or a year. And other people rightfully counter about how noisy it is in small sample sizes.
Well, across 15, 20 years, it becomes maybe the truest signal possible of the average impact you had on how well your team played, unbiased by the box score.
RAPM is like on/off, but it accounts for context: it estimates a player’s impact while controlling for who else was on the floor (teammates and opponents) and what lineups they faced. By using lots of possessions and regularization, it also shrinks noisy estimates so you don’t over-credit “lucky” stretches or small-sample lineup effects. It’s also the training basis of all the top advanced metrics today: EPM, LEBRON.
Across his 20 year career, CP3 has the 3rd highest career value of all time (+9), only behind LeBron James (+9.3), and Jokic (+9.7, who since he’s 30 has yet to decline, which inflates his value relative to LeBron and CP3’s sample size)
