James Harden dropped 40 on the Raptors and added double digit assists to the stat sheet. But he also played defense like this in a 2 point game.
Harden's style of defense seems to be spreading to his teammates as well. Before his sorry attempt at defense Dwight Howard let the dribbler blow past him too.
I'm not sure if the Rockets are teaching this or what is happening, but I doubt you want to clear a path to the rim in order to stop the other team.
