Sortable 82games "Simple Ratings" for NBA Players Out of 178 players in the NBA, Ibaka is 37th in opponent production (5th amongst PF/Cs behind Marion, Howard, Chandler, and Bynum), and 22nd in net production. He also lead the league in blocks (more than 1.5 ahead of the next guy). Whether it's the psychological impact or not, he's an important defensive presence. You're right in one regard, though - he's not a great defensive center. His natural position is power forward, where he played about 95% of the time he was on the court.
