Nene, Okafor & Vesely are all poor outside shooters. Ariza OK at the best.
2. WRT Blatche -I read somewhere that he is "seriously getting in shape & trying to resurect his career". Personally I will believe it when I see it. With some veterans on the team, and team looking like a solid playoff team -I can see him getting back.
Their salary situation is actually not bad. In 2-3 years when they need to resign Wall & Beal, Okafor & Ariza will be gone (or resigned for a lot less).
