Jaylen Brown and Nike's long-standing feud took a wild turn after the recent handshake incident involving Brown and Giannis Antetokounmpo.

One of the surprising storylines in this early NBA season is a budding feud between Boston Celtics superstar Jaylen Brown and two-time MVP Giannis Antetokounmpo. The pair clashed during the Celtics' win over the Milwaukee Bucks on Sunday, which culminated in Brown calling Antetokounmpo a "child" during his postgame press conference.

Antetokounmpo went berserk in Milwaukee's 127-120 overtime victory over the Pistons. His 59 points came on a hyper-efficient 21-of-34 shooting from the floor and 16-of-17 from the charity stripe. Plus, he added 14 rebounds, seven assists, two steals and three blocks, impacting the game at a high level on both ends of the floor.
