The Dallas Mavericks have a terrible 2-13 record after 15 games, and they are expected to be at the bottom of the NBA league standings when the 2017-18 NBA regular season ends in April.

Mavericks head coach Rick Carlisle has already been asked several times about potential changes to his playing lineup, and that is something he's considering with his struggling team. Making changes to the roster is also a possibility the Mavericks' front office will look at as an option.

"I think we're pursuing anything and everything out there," Carlisle told The Dallas Morning News. "At 2-13, pretty sure we're not standing pat. But my focus is the guys we have right now and helping them fight through this and get better."

The Mavericks currently have Seth Curry (left tibia stress reaction), Dorian Finney-Smith (left knee quadriceps tendinitis), Devin Harris (bruised ribs) and Josh McRoberts (lower extremity injury) dealing with injuries, which has also impacted Carlisle's playing rotation.

On Dec. 15, over 90 players who were free agents last summer become trade-eligible, and Dallas might look to make a deal around that time.

One player who could be shopped is center Nerlens Noel. Noel re-signed with the Mavericks as no other suitable offers in the summer came his way, and he's struggling so far this season. In 14 appearances, Noel is averaging just 15.2 minutes, 4.7 points and 4.9 rebounds.

Noel's deal is just for the 2017-18 season, so he can't be traded without his consent. If Noel is traded, he will lose his full Bird free-agent rights, which is why he has full veto power.

Others who might be put on the trade block include Harris, Wesley Matthews, McRoberts and Jeff Withey.

Dallas is currently operating as an "over-the-cap" team due to all the exceptions it owns, but just counting payroll, it is $12.5 million below the cap. The cap room does give the Mavericks a lot of flexibility in the trade market.
