Dirk Nowitzki reportedly agreed to a two-year extension with the Mavs on Tuesday.
He also weighed in on Kevin Durant picking the Warriors in free agency.

"Kevin is all about winning," Dirk added. "He was close a couple of times, but maybe he feels the pressure to win a championship."
The Thunder lost in the Western Conference Finals in 2011, the NBA Finals in 2012, the Western Conference Semifinals in 2013 and the Western Conference Finals in 2014 and 2016.
Oklahoma City missed the 2015 playoffs after Durant underwent season-ending foot surgery.

Nowitzki, who signed a team-friendly deal back in July 2014 to help the front office sign free agents, also offered his thoughts on the Mavs' offseason.
"We got Harrison Barnes, Bogut and I think the brother of Steph Curry," the 2011 NBA Finals MVP added. "It was a good day (Monday), but now let's wait and see how the team fills up. Then we will work on my contract.
"Those are details to be worked on. But we will find a way for both sides to be happy and then I will end my career in Dallas."
