Bottom line I would bring Ray and KG back on a one year deal. What's the point? The worst way to grow IMO for most of these guys would be just throwing the young guys into the fire. Some of the people who are saying to build around Green, it's tough to gauge how he will be coming back from his heart ailment. Here is what I would do
Starters
Rondo
Bradley
Pierce
KG
(Free Agent)
6th man
Ray Allen
Bench
Bass (on 1 year deal)
Moore
JJJ (will get more rotation minutes)
21st pick
22nd pick
Green
Steamer
You never know what will fall to the Celtics with these picks...might be the least popular scenario for 90% of you guys but how many people threw in the towel after 10 games this year? You wanted youth well that would probably be the youngest bench in the league outside of Ray.
