Well heres how I look at it how he effects the Celtics
Rondo is 26, not even close to his prime, and extremely expirienced.
Bradley is 21, and getting great expirience
Jeff Green is 25 years old, only played 4 seasons, and has no health concerns OTHER than the heart problem, which he should make a FULL recovery.
To be honest, having these 3 players as part of your core is a great thing.
Don't mention Stiemsa, he is nothing special besides a good backup Center.
Those 3 players are so unique and talented, there really is nobody even similar to Rondo, Bradley, or Jeff Green. Thats one fast 1,2,3.........scary fast
