I bet the guys you named crack the top 70 out 75 in either offense RPM or defensive RPM unlike Okafor.
So let's talk about RPM real fast
-It's another one of ESPN's patented "made up stats" that they brought into the year 2014
-No one outside of ESPN knows what the formula for this stat is
-Since I check a lot of advanced stat shit out, Im a little knowledgeable about it, and I dont think Ive ever seen anyone ever use that stat in my life outside of ESPN
This is the horse you came riding in on. Hell, you couldve used VORP in which Okafor is the 457th or many other advanced stats that shit all over Okafor. A problem I have with solely depending on stats is that they don't really show how "impactful" a player is. In the instance of VORP, Pau Gasol is ranked 14th in the NBA. Do teams have to worry about Pau Gasol anymore? This is in comparison to Demarcus Cousins who is the 32nd ranked in VORP and is literally one of the most dominant big men in the game right now. Teams will focus practically all of their game plan usually on trying to stop Cousins.
Okafor is that guy for the Sixers, which literally no other Rookie in the NBA has to deal with the load he carries. He's very inefficient with the ball, but his starting guards are Ish Smith and Nik Stauskus. Stauskas is one of the worst defenders ive ever seen in my life, Ish Smith is one of the least efficient shooters Ive ever seen. Not only that, their Half Court Offense is literally the worst one ive ever seen in my life and he's a primarily half court player.
Overall, anyone who has watched Okafor knows he's one of the best 3 best rookies in the league right now. (I'd put him above KP imo but that's a tough one) He's an inefficient player right now, but he's 19 shouldering the load of an NBA team who is literally one of the worst teams to ever exist with literally one of the worst backcourts to ever exist in the modern NBA.
