It used a very-long-term Regularized Adjusted Plus/Minus (RAPM) as its regression basis, used "advanced box score" metrics (i.e. This shows up most obviously in the value for rebounds--a defensive rebound is worth quite a bit to the team, but the individual value assigned above is small (or almost nothing, for point guards!) Even with all that in mind, it's hard not to get lost in what Wood did this season. S.F. Assists are worth far more for a post player than for a point guard. The eye test didnt quite match the numbers Jokic was generating, and many people had concerns that he would never find the confluence of stats and eye test. Not only do the Philadelphia 76ers prevent shots at the rim at an elite clip, they also rebound at an elite clip when hes out there. I embrace it as a competitor, Wiggins said after he also scored a team-best 17 points on a rare poor shooting night from Curry. That ranks in the 93rd percentile among all NBA players, meaning Jokic is elite at preventing shots at the rim despite being unable to jump over a phone book. At least that what I would figure. The background on him was that he wasnt a worker, which is a big reason he went undrafted in 2015.". Any time you evaluate an NBA player, the weight should be 80/20 offense/defenseNOT 50/50, which is what most people believe.

A player like LeBron is playing in different positions and substituting for very different players than he used to, and adjustments like that can give models fits. It's not normal fora player to dunk as much as Wood did this season while shooting as well as he did from 3. As Siakam spun into his patented turnaround jumper from 19 feet, Wiggins perfectly contested the shot without fouling, forced a miss and secured the Warriors sixth victory in eight tries. Narrow regression basis. Offensive and defensive measures may be separated from RPM: Real Plus-Minus Offense: (ORPM): The average effect of a player on his teams offensive performance, measured in points per 100 offensive possessions.

Add a constant (the "team adjustment") to the raw BPM of all of the players on the team so that the team's total sums to the team adjusted efficiency. Your example works better if you give Giannis + 6 for each and then say Jokic at +10 > Giannis at + 12. Not a data scientist nerd so just speaking colloquially here. However when you look at the Career Leaderboard for Defensive Box Plus Minus you will find great defender after great defender.

To adjust for this, we must estimate what the teams average lead was, and then add or subtract one half of the effect (the other half is assumed to belong to the opponents). On some metric (this is a simple explanation), Jokics legendary offense can be +10 and defense +0. Big centers who protect the rim don't often have the athletic bona fides to generate their own offense, and it's hard to have a good enough handle or speed to make drives if you're really tall. But, he is the de facto leader of his hometown team and is the one that receives all off the praises when they are riding high. Defensive rebounding is separated from the overall conversation by some, but certainly ties in and has some predictive value for defenders. Thus LeBrons overall Raw BPM in 2017 is 18.7 - 3.1 = 15.6.
