This year
Kyrie and Luka on - +2.95 Net rtg (286min)
Luka on Kyrie off - -3.5 Net rtg (274min)
Kyrie on Luka off - +5.6 (142min)
Last season in the small sample size, +7.64 with Kyrie on and Luka off (319min) +1.94 with just Luka (1800min)
Luka has been averaging 30-7-7 but his impact does not seem nearly as high as Jokic who is averaging similar numbers, now obviously Jokic is much better but the point is the numbers are similar yet the impact is not close at all. Now this could be because his defense is dreadful but either way there is something missing
Also Livelys impact has been huge with - +5.67 Net rtg (337min) with him on the floor and -2.11 Net rtg (431min) with him off
As a Luka fan, I think the biggest difference is that a solo Luka offense is far more predictable than a solo Kyrie offense.
Everybody on the court knows Luka is gonna have the ball in his hands and try creating everything. Whereas with Kyrie, he doesn’t mind deferring to teammates like Hardaway which keeps things unpredictable. When Luka is on-fire or teammates are making the shots he creates from the attention he draws, the Harden-style of offense works great. Otherwise, it can be stagnant.
And obviously defensively, Luka is extremely inconsistent in his effort and the Mavs don’t have DFS or Maxi Kleber from a couple years ago to hide his flaws. Kyrie isn’t good either, mainly due to size, but he does try a lot harder than Luka on that end.
That said, Luka is still a top 5 player for his talent and individual achievements, but his impact is not nearly enough to consider him in the best player convos.
