Mention some of DeMarcus Cousins' less-than-flattering statistics from last season and you won't hear any excuses for them.Cousins doesn't blame his teammates' inability to catch passes for averaging 3.3 turnovers, ninth-most in the NBA. Nor is there complaining about officiating as a reason Cousins led the NBA with an average of 4.1 fouls per game.Then there's the 43-percent shooting from the field, especially bad for a 6-foot-11 center. Cousins begins his second season tonight against the Los Angeles Lakers with plans to improve all those numbers.Maybe the officials will give Cousins the benefit of the doubt. He also should know what he can get away with when it comes to contact on the court. Cousins, however, knows all improvements begin with him."I'm actually hoping for all of that," he said. "But it's really just me playing smarter. But I've got to play a lot smarter."
