As the start of free agency approached, Kyle Lowry was regarded as the Dallas Mavericks' "Plan A" with Tim Hardaway Jr. being viewed as a priority to re-sign. 

A lot has apparently changed since then... 

Not only is Lowry almost certainly headed to the Miami Heat in free agency as has reported, there is more to the situation that could prove to be a real problem for the Mavericks. 

As reported first by Five Reasons Sports, the Heat also are working to not only land Lowry, but also take acquire DeMar DeRozan, who is considered among the top options for the Mavericks to pursue this free agency.
