If the C's can land 1 or 2 more rotation players, this could be one the the deepest teams they have had in years.
As is, the starters are returning: KG, PP, RR, BB, AB.
And then the top 3 bench guys have the potential to be be very very effective: Jason Terry, Jeff Green, Jared Sullinger (i expect him to be a PLAYER in his rookie year, at least as good as Powe or Davis were as 1st/2nd year players.) That is a very solid 8 man rotation.
That 3 some, if healthy will be much better than the injuried Pietrus, Ray, Stiemsma.
Now the C's need more depth to cover inevitable injuries. With 2-3 more players (say Pietrus, Dooling, Kristc), the C's will easily be on target for at least 50 wins, and should be a top 3 team in the East.
