Williamson is listed at 6 ft 6 in (1.98 m) tall and weighs 284 pounds (129 kg).[117][118] Despite his heavy weight for a basketball player, he is known for his speed and leaping ability.[119][120] NBA player Kevin Durant described him as a "once-in-a-generation type athlete" while an anonymous college basketball coach labeled him a "freak of nature".[121][122] Williamson plays the power forward position but is also capable of being a small-ball center.[123] However, he is best played as a forward due to his size.
