Somebody on the Thunder might want to put a muzzle on Serge Ibaka. Because, for the second time in less than a week, the Thunder forward is firing off shots at the Heat. Last Wednesday, he took Shane Battier to task for being the "biggest flopper" on Miami. Now, he's taking aim at a much bigger target: LeBron James.

"LeBron is not a good defender," he said yesterday. "He can play defense for two to three minutes but not 48 minutes…LeBron can't play [Durant] one-on-one. They're playing good defense like a team."

If anyone knows anything about playing defense, it's Ibaka. But, c'mon, man! LeBron received the most votes for the NBA All-Defensive Team this year. Stop throwing rocks at the throne.
