Having not seen much of Wilt (other than the odd grainy clip on YouTube) it's how I imagine he looked at the time relative to the competition.
Wemby is definitely the biggest freak since Wilt. Pull up 3s from the logo, ball handling skills, easy one handed alley-oops, all while being the clear best defensive player out there. He really changes what it means to be a 'unicorn' after the most recent 'unicorns' like Porzingis, Giannis, Embiid, etc.
