As of now, Oladipo is one of the few Thunder players who are above-average on both the offensive and defensive end. Oladipo, Andre Roberson and Russell Westbrook are the only every-day players (sorry Kyle Singler) with an offensive rating above 100 and a defensive rating below 100.
Dipo gets the wonderful assignment of guarding a team’s second-best perimeter player every night. The Thunder need Westbrook to conserve as much energy as possible on the defensive end. So the OKC perimeter players fluctuate on the positions they guard on a night-to-night basis (with Roberson ALWAYS taking the best player).
