The Thunder’s 90-87 loss to the Lakers on Sunday is a great example of why Russell Westbrook holds the championship keys for this young Oklahoma City team. He posted 22 points, six assists and six rebounds, but turned the ball over seven times, including two bad turnovers in the final minute when the Thunder were trying to complete a comeback.

He’s super-aggressive and supremely talented, but the bottom line is that he’s a scoring guard playing the point, and he has to learn to keep himself under control, especially when he’s attacking the rim and there are defenders in position to take the charge. Unfortunately, his turnovers are actually up this year (3.8 vs 3.3 last season) so it doesn’t look like the light is going to go on anytime soon. He’s actually tied with Rajon Rondo with the most turnovers per game this season.

Can the Thunder emerge from the West? I think they can, but they’re going to have to play better offensively than they did on Sunday. OKC took the Lakers to a Game 7 last year, and once they get Kendrick Perkins into the mix — he sat out of Sunday’s game with sprained knee — they’ll fare better against the Lakers’ big front line. Serge Ibaka looks more than capable of playing power forward, while James Harden and Nick Collison anchor a very capable bench.

Believe it or not — even with the best scorer in the league in Kevin Durant, the Thunder have trouble executing offensively. Westbrook is not a natural playmaker so when he’s penetrating he’s looking for his own shot. The Thunder will probably have to play Harden at the two down the stretch if Ibaka and Perkins are also on the floor. Otherwise, the defense will be able to focus on Durant and Westbrook.

If Westbrook can raise his game and increase his assist-to-turnover ratio from the current 2.2 to 2.8 or 3.0, the Thunder will be very, very dangerous come playoff time.
