Brad Rowland was wailing about this for over a week.
Trent had reached his max games played (active) number and was just sitting on a 2-way contract holding up a spot -- with no way to play more games without being added to the full roster for the remainder of the season.
He gets sent to the G-League, balls out in front of Korver, gets signed to the full roster a day later.
Kind of a baffling way for all this to unfold.
