Ball security: D. The Thunder had 18 turnovers, leading to 23 Memphis points. The Grizzlies had eight turnovers. That's your ballgame. The Thunder has to value the ball more.
Finishing: D. The Thunder shot less than 50 percent (19 of 43) from the paint, including 19 of 37 from the restricted area around the basket. Russell Westbrook was 4-of-14 from the restricted area.
Post defense: B. I know, it looks bad when Zach Randolph and Marc Gasol combine for 54 points on 21-of-33 shooting. But 13 of Randolph's and Gasol's baskets came on jumpers outside the paint or on tip-ins. The Thunder didn't get bulled on the block, it got bullied on the boards.
Defensive rebounding: D. The Grizzlies got six tip-in or putback baskets, which accounted for 12 of their 22 second-chance points. Memphis rebounded 17 of its 43 missed shots or foul shots.
Offensive rebounding: B. Lost in the rout was the Thunder's attack of the boards. OKC rebounded 16 of its 44 missed shots or foul shots, leading to 18 second-chance points.
Kevin Durant: A. Let's see. Randolph was the star of the game; he had 34 points, on 22 shots, and 10 rebounds, two assists and three steals. Durant had 33 points, on 21 shots, and 11 rebounds, three assists, two blocked shots and a steal.
Russell Westbrook: C. Westbrook had quite a line — 29 points, eight rebounds, six assists. His seven turnovers are unacceptable, considering the Grizzlies had eight as a team. But Westbrook's 9-of-23 shooting was not a big factor; he was 7-of-15 before the final nine minutes, which were largely played in desperation mode.
Supporting cast: D. No Thunder other than Durant, Westbrook and Serge Ibaka scored more than five points. James Harden was a virtual no-show, with just five points, all in the fourth quarter. The Memphis bench outscored the Thunder bench 27-16
