Point Guard - Rajon Rondo (Under Contract)
Combo Guard - Avery Bradley (Under Contract)
Shooting Guard - Ray Allen ($4-5M/year deal)
Swingman - Mickael Pietrus (Vet Minimum)
Small Forward - Paul Pierce (Under Contract)
Stretch Forward - Jeff Green ($5M/year deal)
Power Forward - Josh Smith (I don't know how to acquire) -> probably combination of S&Ts + Draft Day Trades + Future Picks
Forward Center - Chris Wilcox (Vet Minimum)
Quick Center - Kevin Garnett ($8M/year deal)
Enforcer - Joakim Noah (I don't know how to acquire) -> probably combination of S&Ts + Draft Day Trades + Future Picks
With Regards to Noah and Smith, I know they're a long shot but one can dream right?
Somehow I think this roster can be pulled off with the right moves: creativity from Danny Ainge's part + Ray Allen, Jeff Green and Kevin Garnett taking lesser salary.
