At 40 years old, San Antonio Spurs big man Tim Duncan knows every trick in the book -- a fact Oklahoma City Thunder center Steven Adams learned the hard way when he was rookie.

Speaking to reporters before Oklahoma City's second-round series against San Antonio, Adams told a story from his rookie year when Duncan pretended to be nice to him, only to then score 20 points on the unsuspecting Thunder center.

Adams' plan to not even engage with Duncan in the second round seems like a sound one, especially since the Spurs center roasted him so bad in their first meeting.
