People are just impatient with Samanic. He just turned 20. He played U17/18 basketball in Europe, he didn't play Euroleague. so the G-League is tougher compe ion than what he had to face in Slowenia. He bulked up before the draft. He bulked up some more in preseason. I assume he's still bulking up. He's versatile and has a high ceiling. It makes sense for the Spurs to draft players with a higher ceiling instead of immediate contributors. This team is rebuilding on the fly, we are not in win now mode.
Brandon Clarke is better right now, but he played 3 years of college ball. He didn't even have a jump shot last season. Samanic has significantly better G-League stats than Clarke had in his first college year.
If he has a good summer league and then plays another season in the G-League he should start to dominate there. Spurs can bring him over in 2021 when he will be 22. I think he has the potential to be something like Andrei Kirilenko which would be valuable as
