The Davis and Beal talk is wishful thinking, obviously. The "next KG and Ray" would be, as others have pointed out, ~30yo all-star vets who have been stuck in bad situations and are hungry for a chance to contend. The existing candidates that might fit that description are Lamarcus Aldridge (though his situation seems to be turning around), Kevin Love (though he is a little young for the part), Carmelo Anthony, and that's about it.
Who else is cast in this little re-enactment? Rajon Rondo is Paul Pierce, Sullinger is Al Jefferson, Kelly Olynyk is Wally Szerbiak mixed with Brian Scalabrine and Leon Powe, Phil Pressey is Sebastian Telfair, Avery Bradley is Tony Allen, Kris Humphries is Theo Ratliff. I guess Vitor has to be Kendrick Perkins.
