Dallas has struggled to defend the rim in their first round series against the Blazers, allowing 18 paint points in the final 12 minutes of Game 3.

"There are opportunities to take hard fouls that we have not taken advantage of and we're going to have to be more physical tonight than we were in Game 4," Mavs coach Rick Carlisle said. "Again, it's all about playoff basketball. It's not about hurting anybody or anything like that. But, a physical series, you've got to be physical."

Chandler has gotten himself in foul trouble throughout the series, but have come on hard few fouls in the paint. In fact, Portland has been exceedingly efficient scoring inside the restricted area of the paint, converting at a whopping 70 percent, according to numbers crunched by NBA.com, when Chandler is on the floor. That percentage drops to 55 percent when he isn't.

The 70 percent figure would have led the NBA this season.
