Miller most recently played for the Clippers' G League affiliate on Thursday, but his hip injury limited him to 14 minutes. Miller's availability does not impact fantasy basketball, especially with Kawhi Leonard available to play.
Mann fractured his finger during an early December game against the Trail Blazers and has not played since. He'll provide depth off the bench, with Jordan Miller likely to player fewer minutes. As for whether or not to roster Mann, he's a player who should remain on the waiver wire in most leagues.
