rondo is un-tradable. I believe ainge said this in an interview once.
Except for Chris Paul
Well I mean... literally just a year ago we tried to trade Rondo for Steph Curry, but Golden State turned us down according to ESPN:
"In December, the Celtics had discussions with Golden State about a Stephen Curry-for-Rondo deal, and one source says it was Golden State that decided against pulling the trigger. But Curry's recent ankle injuries, which have caused him several problems in his short career, have given the Celtics pause."

Curry was still on his rookie contract and would have give us like 41 million in cap space to go nuts.
Then of course there were strong rumors we tried moving him for Pau Gasol...
Rondo isn't untradable... but pretty unlikely we move him.
