Ok, Basketball Jones was a nice try, but not the best pick here.

Gentlemen, let me introduce to you, one of the biggest steals of the Ultimate Draft:
Ethan "Bubblegum" Tate, Cartoon Character
"Pitiful ballplayers of Earth, I am Ethan "Bubblegum" Tate, commander of the Harlem Globetrotters. For generations, your puny planet has lived in peace with the Globetrotter Homeworld. But now, for no reason, we challenge you to defend your honor on the basketball court." ―Bubblegum Tate

Ethan "Bubblegum" Tate is leader of the Harlem Globetrotters, the finest minds (and best basketball players) in the universe, and ruler of the Globetrotters Homeworld.
And "Bubblegum" has to be the best nickname for a basketballer ever.
