Is this ranking the actual best players on the court or top 10 most accomplished players ever?
Kobe would be more accomplished but not the actual better player.
He was listed as 6'11" last year as well on nba.com. He didn't grow as much as people say and Sengun even said so as well saying people just forgot how tall he is in the offseason.
Here is a video last year of Sengun and Jonas Valanciunas literally nose to nose and Valanciunas is listed as 7'0". Sengun is 6'11" but like you said he has a long neck (similar in a way to Bosh and Tyler Hansborough) but his shoulder height is lower and you can see a big shoulder height difference between Jonas and Sengun in that video.
The top 5 you have listed is interchangable. Scottie and Sengun have very hot starts to the season and could make an argument for number 1 and 2 if they continue playing like how they are but if it was last year they not in contension for the top.
Sabonis is very strong and heavily favours his dominant left hand. He also gets most of his assists from handoffs and cutters. Sengun is one of the most ambidextrous players in the league and he generates offense and does pg style assists. He is maybe even bolder with his passes than Jokic is. Sengun is much more similar in style to Jokic but is arguably even more pg like due to him diving and kicking out or diving and dunking a lot.
