Watch: Shaq gets annoyed when Charles Barkley leaves him off his all-time top-10 list

The NBA has a long history of great rivalries, and the best rivalry in the modern NBA may be between two guys who haven't played in the NBA in over a decade: Charles Barkley and Shaquille O'Neal. The "Inside the NBA" analysts are legendary for their constant bickering, and they got into it once again when Barkley listed his top-10 NBA players of all time and left Shaq off entirely.

The argument began when Barkley explained that LeBron was not in his top 5 for all-time NBA players and he listed his top 10: Michael Jordan, Oscar Robertson, Bill Russell, Kareem Abdul-Jabar, Wilt Chamberlain, Kobe Bryant, LeBron, Jerry West, Elgin Baylor, with Bird and Magic tied at 10. Shaq noticed that he was not on the list and he was predictably annoyed.

"Are you kidding me, Chuck?" Shaq asked. "I’m not in your Top 10?”

Kenny Smith asked Barkley to defend his decision, asking if he had ever seen anyone play like Shaq.

"I've never seen anybody like Shaq, ever," Barkley explained. "Shaq is the most dominant big man ever, in my opinion. But I put him behind Magic, Bird, LeBron and Kobe. I didn't put him behind anybody crazy."
