In this Season of the Triple-Double, the reserves of energy in Russell Westbrook's tank, and the mental focus that goes into his craft have been on full display.

On the back end of a bad Thunder road trip, Westbrook extended the game into overtime against Orlando with a 31-foot 3-pointer. By then, he'd already eclipsed his season average in minutes by two. He'd added 20 consecutive minutes without a turnover.

“He puts his stamp on every play," Thunder assistant coach Maurice Cheeks told The Oklahoman. "You don't not see him. How many guys can you say that about?”

With all the responsibility packed into Westbrook's 31.8 points, 10.6 rebounds and 10.4 assists per game, how can the toll of averaging a triple-double not weigh on him mentally and physically?
