The Dallas Mavericks missed their best shot at trading D'Angelo Russell last Tuesday, as the NBA's re-aggregation deadline passed on December 16. Now, whatever team trades for him can't combine his salary with another player's within a different trade. Dallas can still trade Russell ahead of the February 5 trade deadline, but trading him at the beginning of last week would've been ideal.
It would've given interested teams an easier out if he weren't the player that they were looking for, as rerouting a player after trading for him earlier in that season isn't as easy as it seems.
