On the downside, Biyombo is a very poor passer. He registered an assist on just 4% of his possessions, ranking him amongst the worst in this category in the ACB.Hmmmmmmmmmmm No - I don't think I want him at 6, maybe at 12.
His desire to make his presence felt, while an admirable trait, tends to work against him in this regard, especially when looking at his turnover rate, which is fairly high relative to his usage.
This is where his lack of experience shows the most. It's not rare to see him barrel into opponents, get called for traveling violations or have the ball stripped due to his somewhat weak hands. Additionally, he doesn't show anything resembling a jump shot at the moment and converts just 53% of his free throw attempts. While his touch is not bad, his shooting mechanics are a bit rigid, something he'll need to work on to become at least a capable threat from the mid-range area.
Everyone outside of Irving has some major flaws. These are valid points, but they don't knock him out of the 6th slot in this weak draft.
If you look at the entire picture he is still a valid choice at #6.
