I realize trying to work through this with some folks in a logical way might be ignored but here is a shot at it, similar to what others here have done:
1.Lets pretend we sign Brad Miller but don't use the full mle.
2.Lets say we don't know enough to factor in Sheeds contract or PP's contract change but lets say we resign Ray and several factors allow a 2nde add...bear with me.
3. Lets say we resign TA.
4. Lets say Avery Bradley is good and spells Rajon and also plays the two guard some.
5. Lets say we don't sign Nate, as he seems redundant now, but we do sign a good shooting wing who almost all of us think is pretty good and who can spell Ray...lets call this guy "X."
Thats a tough one but lets say we get it done either through Vet minimum, cap space from PP, Sheeds contract,mle, trade or what have you. Its a reach...maybe
Eventually, towards the playoffs, the team looks like:
Perk(28), Miller(20)
KG(28), Baby(20)
PP(30), TA(18)
Ray(30), X(14)
Rajon(36, Bradley(16)
so that looks solid to me. Granted we are missing Sideshow Bob, but perhaps nothing else.
