Celts deal Rondo/Bass/Jeff Green for George Hill, Danny Granger and Roy Hibbert.
Celts get a legit center in Hibbert, an offensive small forward in Granger to spell Pierce (hopefully his knees are healthy) and a respectable PG in George Hill.
Indy gets a more up-tempo team including a legit PG with Rondo, Green, Paul George, Stephenson, Hansborough, etc.
