Not all player are early bloomers from top 10 of all time and they shouldn't be. You just picked exactly ones and made it look like it's status quo. Siskauskas, Jasikevicius, Valanciunas, D. Sabonis were not making any all tournament teams as young players.
Let Rokas first overcome Kalnietis NT level and maybe then try to compare with ltu basketball legends in lets say 4 years from now.
I think you missed my post. Do your calculations one more time.
My point is very simple. Jokubaitis will be better than Kalnietis and more or less (it can go easily to any way) in the same tier with Jasikevicius. If you don't see it, you don't really see basketball. But relax, you're not good with prospects or figuring out different contexts. Jokubaitis today is basically in the same situation as prime Kalnietis when it comes to Euroleague. Unleash current Jokubaitis for 28mpg in mid tier EL club as Lokomotiv, and he would even today give you probably even more than 9.4ppg, 4.8apg, 11,8pir. I could surely see these numbers even today, more or less. Today Jokubaitis would be starting level PG in Zalgiris. Kalnietis never ever was able to fill this position, even prime Kalnietis when he split ways with Zalgiris and went to Armani (while Jokubaitis last season was able to carry Barca as a starting player when Calathes was injured, he was in double digits playing 20+ minutes and Barca remained winning team). Zalgiris tried to give Kalnietis this position, but he couldn't cope with it. Nor Kalnietis was ever good enough to be solid role player of elite EL team (Kalnietis is good only when you give him full control and full freedom, just as he got in the NT or Lokomotive 20/21 when he was MVP of VTB). Jokubaitis is 4th most valuable player in 2022 EB, being 21yo, right after JV, Domas, Grigonis. In 4 years, he'll be better than Kalnietis in EL by far, and also in the NT too, despite Kalnietis being huge NT overachiever. He's already better role player than Kalnietis ever was in EL. He adapts to different situations better, he reads the game better, he's more consistent and versatile scorer/decision maker. Jokubaitis is 4th most efficient Barca's player in ACB with 10.8pir, and teams really go hard on them. Once Jokubaitis will be finished product physically, and he will get bigger role in the NT, he will be better player than Kalnietis without any doubt, unless his development would be stopped by injuries or some major disturbances.
Have in mind that Jokubaitis in EB with 26mpg, 7,7shots produced 9.3pir and he had a good 13pts, 15pir knock out game against Spain. That's 21yo kid.
Kalnietis 2013 played 32mpg, took 12shots, and had 10,4pir.
Kalnietis 2015 played 34mpg, took plenty shots, 9,7pir.
Just in comparison 21yo Jokubaitis had more efficiency 9,3 than 24yo Kalnietis in 2010 WC 8.1. Both played similar minutes 25-26.
In other words, Jokubaitis is already very very close prime Kalnietis level. And, off course, the game was very different. Jokubaitis wasn't unleashed for full action as Kalnietis. He was often played without the ball, watching Grigonis, Brazdeikis operating, feeding bigs inside. In 2013-2015 everything was going through Kalnietis in the first place. When Jokubaitis will have more tools and will be trusted as the main aggressor and protagonist, his numbers will only go up.
