Ja Morant's new hand grenade celebration has drawn the ire of some of basketball's biggest voices.

The "NBA on TNT" crew discussed the Memphis star Thursday night and shared their thoughts on his controversial taunt.

Charles Barkley brought up the coaching change Memphis made recently, calling out Morant's maturity.

"I know one person happy right now. Taylor Jenkins ain't got to deal with this crap," Barkley said. "He's gonna get another job he deserves and not have to deal with this immature stuff."

Kenny Smith referenced Morant's history with guns and suggested he should leave weapon-based celebrations behind.

Morant debuted the hand grenade on Tuesday against Charlotte. He flashed it again on Thursday against the Timberwolves.

He was on the record saying: "That's my celebration until somebody got a problem with it."

Some big voices in the basketball world have a problem with it, but the league has not taken action against Morant. Until they do, he will continue miming projectiles.
