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.
