There is no way in hell CJ is available as a vet min guy. He will get a 3 years $45m-$50m from someone for sure, and he is worth it. A respected vet, professional that can still drop 50 in a game every once in a while. The Wizards had to get rid of him - they were winning too much with him - and they can sit TY as he has some kind of a leg injury. (They want to protect their top-8 protected pick this year)
If you have a chance at getting CJ at anything less than the $15m/year - you jump on that. He is not good enough to be your #2 guy for a team that has multiple defensive players they have to play (like the Blazers did when he was here), but as a $15m vet for a team that has lots of defensive players (like the Hawks are going to be after this trade) - he would be great. I would be shocked if he is not extended at Atlanta.
