The Dallas Mavericks may be set with their one-two punch in Luka Doncic and Kristaps Porzingis, but they're still doing their due diligence in hopes of adding more firepower. According to Brad Townsend of the Dallas Morning News, the Mavs may try their luck on Tobias Harris.

A league source said on Saturday that the Mavericks plan to submit a less-than-maximum offer for Philadelphia forward Tobias Harris, but the source added that Dallas fully expects the Sixers to “back up the truck” and keep Harris with a maximum contract.

As mentioned, it's not going to be easy for Mark Cuban and co. to land Harris with the Sixers appearing more intent in retaining the versatile forward's services for several more years.

What the Mavs can offer, other than money, is the chance to play alongside what's arguably the NBA's most promising duo in Doncic and Porzingis. Outside of those two, the Mavs aren't in bad shape. For most of the 2018-19 campaign, Dallas was in the mix for the final playoff ticket — who knows what a more seasoned Doncic and a healthy Porzingis could do.

Dallas is headed into free agency with over $28 million in cap space compared to the Sixers' $31.8 million.

In 27 games for the Sixers, after being traded midseason by the L.A. Clippers, Harris had averages of 18.2 points, 7.9 rebounds, and 2.9 assists while shooting 46% from the field and 32% from long distance.

For what it's worth, the Mavs may very look into recruiting Boban Marjanovic along with Harris, only for the sake of the “Bobi and Tobi” fame.
