Agility wise, he is better. He may need some good shooting skills for him to be unstoppable at the perimeter. More like a Yao Ming type of player which will be difficult to reach once he stretched those arms of him.
Develop the patented Jabbar's skyhook and this kid would be great as this shot is impossible to block.
Now they got a good and tall center, they will just develop him to cope up with the bigs of NBA. If this can shoot on the perimeter and even threes, this young player can beat Embiid and other bigs. I know that this is not as fast as Giannis but I think he can dominate the paint because of his length. Jabbar v 2.0?? It will be very handy if he knows how to do it
