The Dallas Mavericks have made notable offseason moves, including the addition of D’Angelo Russell and the drafting of Cooper Flagg. Their latest signing is Dante Exum, who returns to bolster the backcourt following Spencer Dinwiddie's departure to Charlotte. Exum's defensive skills and versatility are expected to provide relief in a thin backcourt, but his signing complicates roster management, as the team must reduce their contracts from 16 to 15. Amid speculation of trades involving Olivier-Maxence Prosper, the Mavericks look to navigate this roster crunch effectively.
