You could do Rondo for Knight, Monroe, Kravtsov. You can expand it and throw in Courtney Lee and take back Stuckey, which shaves a couple of years of contract you owe.
They would have Rondo, Caldwell-Pope, Singler, Smith, Drummond. If you could get their unprotected #1 pick, there is a chance they could be bad and it would be a good pick. A rookie shooting guard in Pope, Drummond is still developing on offense. If Smith takes a million hero shots, they could be a mediocre team.
Knight, Bradley, Green, Sullinger, Monroe along with Olynyk gives the Cletics 6 B or B+ level prospects. Monroe may be an A- player and Olynyk could develop into one. The main thing is getting 2 chances at getting the ping pong balls to drop right.
