LeBron James had some free time this week during the NBA All-Star break, and he used some of it to take aim at Doug Gottlieb on social media. The Los Angeles Lakers star quoted a post Monday morning that noted how Wisconsin-Green Bay, for which Gottlieb is a first-year coach, hadn’t won a game in three months.

Gottlieb, who is also a radio host for FOX Sports, responded as he called into a show on the netowkr Monday to address the jab from James. He accused the 21-time All-Star of “punching down” by criticizing him and his team.
