Answer Guys: How to handle Boozer and Sheed

I have Carlos Boozer on my team. I have declined trades for him all season long and now he is out for another three weeks or more. Should I trade him for a lesser player to at least get some production out of Boozer's roster slot? Or should I just drop him and pick up a player off the free agent list? It sounds like a bad idea to just outright drop Boozer, but last year I held on to Luol Deng and I got burned big time. I really don't want to do this, but there are some free agents I have been keeping my eye on, including Hakim Warrick. Warrick has really stepped up his game, but his playing time hasn't been consistent. Is that a move I should make? Eric
