The Dallas Mavericks are having a tough time heading into this season as they've lost two pre-season games by a huge margin.

The main reason is that most of their starters are not ready to see action and many are still adjusting to the system.

With that said, Dirk Nowitzki spoke with Dallas News and he said that the past two games have been disappointing, but he is not blaming anybody as he understands that some guys on the roster just came off major surgeries and pushing them to get back on the court is not a good idea.

"It's disappointing," Nowitzki said. "Honestly, you'd wish more guys would be doing more, at least more contact or run more. But that's not the case. Some of these guys have had major, major surgeries. And whatever the doc tells them, you got to take it slow."

"Obviously, Parsons and Wes are both guys that want to be here for a lot of years. It would be wrong to push it too much in October and not have them later in the season. You want to take it slow and progress week to week, and whenever they're ready, they're ready."

Also, he believes that their offense will take some time to develop as their court general, Deron Williams is still learning the whole system.

"It's not optimal, especially when you have a new point guard [Williams] trying to learn the system," Nowitzki said. "You can run all the five-on-oh you want, but until you practice and play with each other, it's not going to help much. But we're doing all we can to get everybody used to the plays and the calls."
