Isiah Thomas wasn't happy to see Los Angeles Lakers superstar LeBron James warming up shirtless before the game against the Houston Rockets. The former NBA player-turned-analyst feels that it's unprofessional coming from the face of the league and further proof of how lenient the NBA is towards its players.

NBA legend Isiah Thomas criticized LeBron James for practicing shirtless before a crucial game against the Houston Rockets, deeming it unprofessional and urging the NBA to fine him. Thomas argued that such behavior diminishes the league's professionalism.

Long before Isiah Thomas blasted LeBron James for warming up on the court without a shirt before a game, the Detroit Pistons legend crowned the Los Angeles Lakers star as the "G.O.A.T."
