Per Rod Beard of The Detroit News:
Firstly let’s clarify a few things here, his contract becomes fully guaranteed if he is not waived before the 1st of July, so it will be a nervous few weeks for Darrun Hilliard. However with a reported salary of roughly $1.4 million, it won’t really free up a lot of cap space. What it would do is free up a roster spot for the Detroit Pistons to take a chance on an undrafted prospect, or potentially take back two players with one player going out in a trade scenario.
