Russell Westbrook could become the first player in 55 years to average a triple-double over a season. A growing emphasis on 3-point shooting, aided by rule changes that encourage more outside activity and a growing sense that potential rewards from beyond the arc outweigh the risks, have seen the NBA evolve into a haven for long-range sharpshooters and versatile playmakers. Oklahoma City star Westbrook leads the NBA with 31.4 points a game and averages 10.6 rebounds and 10.3 assists in a bid to become only the second player to average a triple-double for a season -- Oscar Robertson achieving the feat with 30.8 points, 12.5 rebounds and 11.4 assists over 79 games in the 1961-62 campaign.
