For fun:
Assume that Danny trades Rondo, and let's say BBD in a S&T, for CP3 (involving Indy, picks, whatever... doesn't matter, just say it happens), now how do you fill out the roster?
I believe Celtics would have the "Mini MLE" ($3M/year), and the Marquis Daniels ~$2M trade exemption.
Here's my first take at this (in no particular order):
(1) sign Jeff Green to QO (I doubt it will be matched).
(2) sign JaJuan Johnson to his rookie deal
(3) offer the vet min to Jeff Foster
(4) offer the $3M mini-MLE to Grant Hill
(5) sign Delonte West to whatever is allowed (last year's salary plus X%?)
(6) Scour the amnesty lists, vet FA role players to fill out the roster with min deals.
Roster:
CP3/DWest/Bradley
Ray/Grant Hill
PP/Jeff Green
KG/JaJuan Johnson
JO/Jeff Foster
