Yup, Celtics will and should trade Rondo this season. He's a great PG, but has only this year and next left on his contract and then will be looking for a huge payday. C's won't be remotely good enough to compete by then so won't make sense to keep him then anyhow.
Trade him this season for best rookies/draft picks they can get.
With the type of talent coming out after next year...how can you not?
