I only view the Green, Lee and two 1st round picks as a small trade because I don't highly value those two players for "our" team.
However, if I'm a GM with a guy who wants to walk and who I'll probably lose, getting a serviceable off guard for my rotation in Lee, a potential starting SF in JG and a couple 1st round picks that are most likely middle of the road picks, I would consider it. There are a lot of factors.
* I do think Green could be a starting small forward but he has to get 35-38 minutes a night - I don't know if his make up is as a bench guy. Didn't he post his best numbers as a starter in the past?
TP to Ogaju - your post summarizes in one small paragraph my thoughts - exactly.
1. I would not mortgage our young guys to put someone next to KG and Pierce so they can "get" one more right now.
2. I would try to make a small trade - the one I'd pursue heaviest would be Lee and a pick if necessary for Dalembert. We just need another half legit 7 foot body inside - along with Bradley outside - and this team will be dramatically better - and in my opinion pressing Miami for the spot in the finals again.
3. Keep your young core of Melo, Sully, Green,Bradley, Rondo and Joseph if possible.
4. Go to the Lottery for one year if you have to
5. Once KG and Pierce come off the books, go after the Josh Smith's as they come available - or whoever you think your guy is.
* That is a very good young core of players to begin rebuilding around and if you do it right you could be back in business in 1-3 years, big time.
Stay competitive now - keep the eye on the long game with holding onto our young guys.
Particularly until they develop more. Both melo and Sully may be infinitely more valuable in a potential trade 18-24 months from now.
