I'd really like a scorer who can play both SG and SF to come off the bench behind Green and Bradley. I've settled on CJ Miles as a good target for more than the minimum but less than the full MLE. I'd use the rest of the MLE to bring in a better backup PG. Steve Blake maybe?
This assumes that Anthony, Bass, Bogans, and one of Sullinger/Olynykand both 2014 picks are traded as part of the packages to bring back Love and Asik.
I'd be happy with a roster that looks like
Rondo - Steve Blake - Pressey
Bradley - CJ Miles
Green - Wallace - Chris Johnson
Kevin Love - Olynyk or Sullinger (whoever isn't traded)
Omer Asik - Faverani
I'd look for a defense-oriented PF as the fifth big and a third-string center who is better suited to match-ups that give Faverani problems.
I'm not married to the idea of keeping Pressey or Johnson and I'd scour the D-League, Europe, and the ranks of undrafted free agents as possible upgrades.
That would be 14 players and I'd like to keep the 15th slot open to maintain flexibility. I would consider bringing back Humphries or Bayless if they signed tradeable contracts.
If all goes well:
Kevin Love is your MVP candidate
Rondo is your second star
Asik is a DPOY candidate
Bradley improves
Green is the weakest link in the starting lineup
Miles will do well in SMOY voting
