I think they both stay for next year as long as the following happens.
1. Pierce is still here
2a. D Howard signs with the Cs
2b. Rondo is traded for a starting caliber C and PG (nash and Gortat, D Harris and Big Al, Felton and Camby)
If option 2b happens we resign everyone (KG,Ray,Pietrus,Bass, and J Green) and have an old but very deep team to make one last final push with. We would also have a young bench group of Avery, JJJ, two 2012 1st (hopefully Austin Rivers), maybe steimsma, maybe moore, and possibly a 2012 2nd round pick.
I really like the Big Al and Harris option, if danny can pull of a draft day miricle and get us a starter caliber rookie sg then we are a good looking team. As the season progresses Ray would ideally go to the bench with the rookie taking his starting spot.
D Harris, Avery
Ray,Pietrus, (River,D Lamb, B Beal)
Pierce, J Green
KG, Bass, JJJ
Big Al, FA (wilcox?)Steimsma
