From a team release:
"AUBURN HILLS, Mich. – Detroit Pistons President of Basketball Operations Joe Dumars announced today that the club has requested waivers on guard Vernon Hamilton and forward Ike Diogu.Hamilton appeared in five games, averaging 0.6 assists and 0.8 rebounds in 3.6 minutes per game. Diogu appeared in three games, averaging 2.3 points and 1.7 rebounds in 5.3 minutes per game."
No surprise here. They were longshots to make the team when they were invited to training camp, and neither played much in the preseason.
The Pistons’ roster is down to 15 players, so no more roster moves need to be made.
