It would appear that the Mavs' desire to tank is over, at least according to rumors being shared by The Ringer's Kevin O'Connor. According to O'Connor, ever since Dirk Nowitzki announced his intent to join the franchise for a 21st season, the team's front office has been discussing ways to get the team back in position to rack up more W's than L's. O'Connor adds that multiple league sources expect them to pursue a trio of big men that include: DeMarcus Cousins, Julius Randle, and DeAndre Jordan (you know, again).
As O'Connor wrote:
Ever since word spread in league circles in March that Dirk Nowitzki would return to the Mavericks for his 21st season, there have also been rumblings that the Dallas front office will look to make additions this summer that can put the team back on a winning track. The Mavericks can create space to sign a max free agent, and multiple league sources expect them to pursue a trio of big men: DeAndre Jordan, DeMarcus Cousins, and restricted free agent Julius Randle. If the Mavericks do indeed plan to pursue expensive bigs in free agency, then it’d make sense to target a primary scorer, like Porter, rather than [Mo] Bamba.
The Mavs also landed the fifth spot for next month's draft, which probably isn't as high as they want but there should still be some talent available.
