This was from about 10 days ago..
Doubt it has changed much.
Okafor is 40th among centers in Defensive Rebounding Rate (Out of 47 qualifying centers). There's some actual big names around him, Mosgov, Gasol, Horford.. But the problem is is those guys contest the paint, contest shots, and often take themselves out of plenty of rebounding situations similar to Hibbert.
43rd when you factor in both sides for Rebounding Rate.
Philly's defensive efficiency has dropped from 12th to 26th.
If 57 points given up per 48 minutes is accurate
Not sure how the moving parts in that add up though. Is Okafor playing center?
