Since Roberson went out, Oklahoma City’s defensive rating
has been 112.3, which would rank 27th in the league, ahead of only the Cleveland Cavaliers, Sacramento Kings and Phoenix Suns. That’s extreme though not unexpected with Roberson no longer there to cover for weaker defenders like Westbrook or Anthony. But here’s the kick in the head:
The team’s offensive ratings has barely budged despite losing one of the worst offensive players in the league, going from 110.9 before Roberson’s injury to 111.8 after it. This is much harder to explain.
Roberson didn’t simply deprive his offense of a player who could do a better job of shooting, passing or dribbling. He shrank the court, allowing defenders to roam guilt-free, to harass ballhandlers and make life difficult for anyone establishing post position or running around off-ball screens.
