Okay, lets think about this question for a moment.
That is a picture of Prime Shaq, 50 something y/o Wilt and Patrick Ewing. We don’t have to rely on the picture to see that wilt is bigger. We know Wilt was measured at 7′1 and 1/8″ in his stocking feet when he was drafted and Shaq was measured at 7′ 1/2″ inch in his stocking feet when he was drafted.
Wilt also played more minutes per game than Shaq. He averaged 45.8 minutes a game compared to Shaq’s 34.7 minutes per game. Wilt also stayed in better shape over the course of his career while Shaq tended to be a little more “padded”. Wilt gets the edge in stamina.
Shaq’s game was built on his ability to overpower people he played against. Shaq struggled against guys like Yao Ming, David Robinson and Hakeem Olajuwan who were able to deal with his strength. Wilt was able to bench 550 lbs in his prime, about 85 lb more than Shaq’s best. Shaq was strong but Wilt’s feats of strength are the stuff of legends…
Then there is athleticism. Shaq was fast for a big man. He once did an exhibition where he he ran against Tyson Gay, an olympic sprinter. Shaq ran 30 meters to Gay’s 60 meters and Shaq covered that distance in 4.86 seconds. Wilt’s measured time in a 40 yard dash was 4.6 seconds.
So Wilt was bigger, stronger and faster than Shaq. Wilt was also more versatile offensively. His turnaround jumper was regularly on display as was his hook shot. Wilt also spent time with the Harlem Globetrotters and was a good enough ball handler for them to feature his as a guard. Finally there was leaping ability. Wilt was a track athlete in college and one of the events he competed in was high jump. Sorry Shaq, you lose this category too.
Wilt would have eaten Shaq alive.
