LeBron James has taken on full dad duties this off-season, travelling to Las Vegas with his son, LeBron James Jr's, AAU team.

Over the weekend LeBron took over coaching duties and made sure to keep the score keepers in check. Earlier this weekend, LeBron returned to his seat in the stands with the other parents, but he was still vocal with his son's team.

In particular, he took issue with the sportsmanship displayed by Utah Elite, and he let everyone in the gym know about it.

Prior to the start of the game, LeBron hilariously yelled to 12-year old LeBron James Jr. and his teammates, "Don’t care about sportsmanship, then … get in their ass like a bike with no seat."

And the LeBron Jr proceeded to break one of the opposing players' ankles.

At one point during the game, the crowd began to yell at the refs after Bronny was hacked on his way to the hoop and a foul wasn't called, but LeBron urged them to quiet down.
