Dirk Nowitzki entering free agency

That’s not a huge surprise, although the Mavericks were hoping talks about a contract extension for the nine-time all-star would come to fruition.

A source confirmed that an extension now is unlikely and that if the face of the franchise is to stay in Dallas, it will happen via a new contract in free agency.

Nowitzki said last month that he would exercise his early termination option and explore free agency. It’s the first time he’ll be free on the open market.
