It's a tie game. The seconds are winding down in the fourth quarter, Kobe Bryant has the ball and a chance to win the game as he attempts a one-on-one maneuver from the top of the key. Why in the heck is 6-3 Oklahoma City guard James Harden guarding Bryant in this situation?
Because it's the middle of August, there's an NBA lockout, and this is the Drew League. Harden is the best NBA player on site, and OKC's Thabo Sefolosha (who has usually defended Kobe quite well) is nowhere to be found.
Also, it's Kobe. He may not execute at the level you'd expect, but he has done this many (many, many) times before. He dropped 45 of his team's 139 points, and he nailed the game-winner on Tuesday night.
