Shagari Alleyne is really big — and he has an enormous head! Eric, did you watch any of the workout? What did you think of any of the participants?
And yeah, he probably has the biggest head of any living human being (circumference wise). His hat size is 8 1/2 which is literally extra-extra-extra large. I have an extra-large hat size.

Yes, I even asked him in person. He can grab the rim one-handed on his tippy-toes (reaching about an inch or two above the rim). He still needs to ‘jump’ slightly (like an inch or two) to get the ball through the hop though.

Visser showed a few nice moves in the post.

Alleyne’s got a 9,8″ standing reach (which btw is the same as Yao’s but Yao’s actually 3 inches taller in head height than this guy) and a 8,1″ wingspan (8 inches longer than Yao’s 7,5″ wingspan and longer than anybody currently in the NBA) but stands only 7,2″ barefoot. He can’t touch the rim standing flatfooted but on his tippy toes, yes. he’s a freak of nature with huge hands, huge feet, long arms, and yes of course, a disproportionately large head for even his gigantic frame!
