S $58 Mil is the limit, and we have roughly $25 Mil to spend after Pierce, Rondo, Bradley, and JJJ.
This is actually really simple, and it all depends on one guy: KG.
If KG wants to play basketball again, he will come back to Boston...IF...we come relatively close to matching any open market offers he gets from other serious NBA Finals contenders. We cannot low ball this guy. If someone offers him $15 Mil, we have to come close to that. It is difficult to know how much KG will get because of his age, but I totally think he is worth $15 Mil for 2 years based on his play this year. So let's just say that we get somewhat of a hometown discount and we sign him: $12 Mil for KG.
That gives us $13 Mil and we only have 7 players on our roster (including the 2 1st rounders.) I think that means Ray Allen is a goner. I would love to see him stay, but my guess is he gets $8M from some team. We cannot spend $20 Mil for KG and Ray and leave only $5 Mil for the rest of our rotation.
Hopefully Bass takes his player option at $4.25 Mil. Let's say he doesn't, we bump it up to $5 Mil. $5 Mil for BB.
Resign Jeff Green at $6 mil.
That leaves $2 Mil. I use that for Stiemer and E'Twaun Moore, plus another veteran at the minimum (Dooling probably.) If we can find a way to get Pietrus in there, either by saving money on the KG or Green contracts, I do it to.
That's all the cap space for next season. We basically replace Ray Allen with Jeff Green and 2 1st round draft picks. I think that puts us around 12-13 players on the roster. That's about as good as Danny could do without making any trades.
