Jabari will be one of those players that’s so good after a handful of years that he’ll need 4-5 nicknames.
Agent Smith is great. I like the ones that flow with the first or last name ie: Clyde The Glide. Air Jordan. Larry Legend. Hot Rod Williams. Kenny Sky Walker. Sir Charles/Chuckster. Hakeem The Dream. Mad Max. Tim Bug. Wilt The Stilt. Pistol Pete. Stevie Franchise. First name replacements like Magic, Penny, Mugsey are dope but seem childhood given. The Admiral, The Mailman, The Round Mound of Rebound, The Big Ticket, The Answer, The Truth, Half Man Half Amazing, The Great Wall, The Iceman, Grandmama, G-Money, The Big Dipper, Mr. Clutch/The Logo, The Worm, The Flash, Diesel/Superman/The Big Aristotle. These are all just standalone names that are cool for trading cards but rarely actually said.
Wait to see what Hollins comes up with in commentary in his first few games, and then don't use that.
