I'd say unless some deal that is just too good to pass up comes long that is... a quality player that could be impact player for years , they have 75% chance of staying.
I just don't see getting back any kind of IMPACT players for them.....we don't need anymore scrubs or role players ( Lees's , Jets , swingmen....we have a team of mostly short undersized guys now

in 99% of the instances i come up with , the Celtics are worse dumping Pierce and Garnet.
They aren't horrible and can still contribute .
Throw rocks at me, but I'd still TRY trade Rondo for a GOOD center and try and draft some point guards
