Domantas Sabonis will be successful in the NBA because he's relentless. People get hung up on physical stats, reach, etc. and forget the most important factors in rebounding: position, reading the carom, timing of the bump, and desire. He always wants to dominate the boards in a game, and is doing so against bigger players now. No reason to think that won't continue in the NBA as he grows and gets stronger. If you've watched many Zags games you know is is a tough SOB, literally a bulldog. But, the biggest upside for me is that Domantas, at age 10, likely knew things about rebounding and screen-setting that some NBA players haven't learned after 5 years in the league.
Learn the scouting, then post. (hahahaha)
