Injuries are the one thing I worry about with Porzingis. Generally, taller is better, but at some point taller becomes suboptimal. KP is right on the cusp of the point at which height becomes a detriment in terms of both health and functional strength. To KP's credit, he moves fluidly and doesn't have any injury history that I know of.
His combination of length, athleticism, and skill are insane. Same with Karl-Anthony Towns. Those guys are going to revolutionize the center position (their best long-term position IMO), in terms of their ability to protect the rim and defend on the perimeter (especially in the pick-and-roll) and make plays offensively.
