Serge Ibaka/Nick Collison combination: B. Brooks found a winning combo by playing these guys together. Collison on Nowitzki allowed Ibaka to roam free, and he responded with five blocked shots and a very good offensive game (18 points). Collison was his usual effective self (12 points, seven rebounds). But they were on the court together during the late meltdown.
Ball security: F. Twenty-five turnovers is ridiculous; 24 came in regulation. Durant had nine, Westbrook six and Harden four.
Bench: C. Outside of Collison, the Thunder backups didn't assert themselves. Harden had just seven points in 23 minutes. Eric Maynor was largely ineffective. Daequan Cook didn't get a shot off in his 51/2 minutes. But maybe Harden's value was abstract; when he fouled out with 4:34 left, the Thunder led 99-87.
