Numbers. I have my personal list of the top 50 players in the NBA, and for me using analytics and basketball knowledge, he isn’t a top 20 player. But for me, he is still a really good player.
But as an example how you can’t take numbers at face value let’s look at RPM. Rudy is a 24th overall with a 2.8 (-.96 offensively, 3.76 defensively). Then you have Daniel Theis at 29th overall with a 2.51 (-1.00 offensively, 3.51 defensively). Do you really think Gobert and Theis are on the same level? I don’t, but the numbers say they pretty much are and Celtics are getting that production for $5 million a year instead of $25+ million and possibly going forward $30+ million.
