I'd say although he looks so slow and weak, he seems to move pretty well at 6' 10" judging from the video. I think the most he would be in the NBA is a Mikki Moore rather than a KG, since he started playing organized basketball late.
I don't think he would be a top 15 on the next draft which is good, because my projection for the Kings on 2009 draft is somewhere between #3 and #7.
OK, where do I start. Lets try this. I watch a lot of college basketball. Something I enjoy, as well as being a hobby. Seeing myself as an amateur scout, I get some vicarious joy out of the success of a player that I thought would make it in the NBA.
I can honestly tell you that there are very few players that I can guarantee will be stars, even after watching 5 to 10 games with that player. In some cases, with a three or four year player, I may see that player play 20 or 30 times. Example: Brook Lopez, and his brother. I believe I saw every college game both of them played. I didn't bother to count. I thought that Brook would eventually be a top ten pick and that his brother Robin could fall into the second round. I also thought that Robin was more talented than given credit for.
This observation came after watching them through two years of college. There is no way I could have come to this conclusion from watching just one game. I watched a young center from Washington, Spencer Hawes come to play Stanford and get his head handed to him by the Lopez twins. Based on that one game, I was not impressed. However later that same year, in a rematch, I saw a fiesty Spencer Hawes hand the lopez brothers their heads.
So, my point is, that after watching a couple of minutes of a player on a youtube film, you have learned absolutely nothing. In fact, on most youtube films, you see exactly what they want you to see. They never miss a shot or a rebound. To predict the future of Majok, based on that youtube is not only ridiculous, but impossible. Unless of course you've had a vision from god.
As far as the young man from the Sudan having very little basketball experience. I would like to point out that another young man named Akeem had only two years of highschool, in africa, and three years of college before entering the NBA. He didn't do to badly. He was a 20/10 player from the get go. Please, I'm not saying this kid is the next Akeem. I'm just saying its possible to overcome the experience factor if you have enough talent and have the desire.
