Millsap is still a decent producer as a bench player. He'll still get a block and close to 10 boards if/when Boozer returns to the starting line. Considering how many guards you have, you can afford to ship Duhon.
Not serious, he just needs rest. He's been struggling since his return but he admitted he was just trying to make it to the all star break so he could rest them. Doctors put him back on the court too soon imo, he would've benefited another couple game's rest. He said it didn't feel right but wouldn't say he didn't want to play.
