Mavericks get two players that have decreased roles on their current team. Well addressing some issues on the team.

Portland mainly does it for the second rounder.

Houston does it for the expiring contracts and the first rounder. The Houston could use all their expiring contracts and other bigger contracts to swing for an elite scorer. Or keep them for the end of the season and create a larger cap space for themselves . Or you could switch those two expiring for Omax /Jaden . Young guys that have some upside.
