Rondo, Ray, Pierce, KG, Jo and Bradley are signed.
JaJuan Johnson and E'Twaun Moore(Not Guaranteed) will be signed as well.
Marquis Daniels, Von Wafer, Gilbert Brown, Sasha Pavlovic, Bostjan Nachbar, Michael Redd, Carlos Arroyo, Troy Murphy, Kurt Thomas, Chris Wilcox, Hilton Armstrong, Etan Thomas, DJ Mbenga, Alexis Ajinca, Kyrlo Fesenko, Joel Pryzbilla etc. can probably be signed for the vet min.
Glen Davis and Jeff Green can be brought back because we have their bird rights. We can also sign and trade these guys to get players out side of free agency.
Kwame Brown, Delonte West, Nate Robinson(if he's bought out), Reggie Evans, Josh Howard, Aaron Gray, Shannon Brown, Grant Hill, Shane Battier, Carl Landry, Josh McRoberts, Yi Jianlian, Chuck Hayes, Chris Wilcox, Anthony Parker etc. will demand all or part of the full MLE available to the Celtics which would be 3 Million for 3 years. Most of these guys would have to take a pay cut to take 3 Million and would get offered more from non-tax teams.
We can probably get a cheap player through the Marquis trade exception from some team looking to shed salary.
We should get
1) Delonte West
2) Two of (Marquis Daniels, Von Wafer, Gilbert Brown, Sasha Pavlovic)
3)Jeff Green
4) Three of (Glen Davis, Chris Wilcox, Hilton Armstrong, Carl Landry, Etan Thomas, Reggie Evans)
I think this would give us what we need to get 18.
