The Dallas Mavericks have a problem. It's not just the 0-2 hole that they are in against the Thunder. It's also the guy who wears No. 0. Russell Westbrook is giving the Mavs fits, and it doesn't look like there's anything Dallas can do about it. Doesn't seem to matter who or what the Mavs throw at him. "He's the guy who's been killing us," Mavs star Dirk Nowitzki said. Through the first two games of this Western Conference playoff series, Westbrook is averaging 28.5 points and shooting 52.3 percent. He's getting to the rim. He's hitting midrange jumpers. He's even knocking down that occasional 3-point shot.
