No way the Bobcats do this.
They essentially lose most of their young players and a pick just for Rondo, who's likely going to bolt in 2 years for free agency.
This MIGHT be a little more realistic
Bobcats get: Rondo, Jeff Green, Bass, Lee, Celts 2016 draft pick from Brooklyn.
Celts get: Sessions, Gordon, MKG, Cody Zeller and Charlotte's 2015 1st rd draft pick.
Bobcats get a star PG and can have Walker come off the bench. A starting lineup of Rondo, Lee, Green, Bass and Jefferson with Walker and Biyombo coming off the bench could be a good one.
Celts get two good young players in Gilchrist and Biyombo and two expirings.
Remember the key here is to assume that Rondo doesn't stick around in Charlotte after he hits free agency.
If he doesn't, then I think what I've proposed is a pretty decent haul for the Celtics and even then I am not sure if Charlotte does that.
This is clearly a deal where the Celts would be all in for the draft and the Cats would be all in for competing.
