Consider the following scenario: Ray departs for less green pastures, so Danny offers Pietrus the BAE to replace him. Bass and Green re-sign for a combined $13 mil in year 1. Stiemsma and Wilcox depart for better offers than the QO and minimum (the most we can offer them without the BAE, I believe) respectively.
Our roster looks like this:
Rondo/Terry/Moore
Bradley/Pietrus
Pierce/Green/Joseph
Bass/Sullinger/JJJ
KG/Melo/Williams
We're @ approximately $66 mil in payroll, leaving us about $8 mil under the apron, but only the vet min to spend. Our perimeter looks very solid (maybe vets like Dooling and Daniels in place of the 2nd round young uns), but the big man situation is really sketchy, with 3 unproven young guys behind our starters and a borderline NBA guy in Williams.
We could go bargain vet hunting, waive Williams and bring in a combo like Joey Dorsey and Magloire - decent options if we need rebounding or veteran post defense in a pinch. Unfortunately, it also means leaving most of that $8 mil on the table (saving the owners the tax, but not doing anything for our competitive prospects).
The alternative I'd propose is forgoing the bargain bin shopping to offer the bulk of the $8 mil to Nenad Krstic using our bird rights. Something like a 2 year $16 mil deal, with the second year partially guaranteed for $1.5 mil (patterned after the deal Houston gave Dalembert).
While Nenad is hardly a good fit for our big man needs - he's a weak rebounder and defender and a relatively low-impact, though useful, offensive player - he's at least a stable contributor (something we can't be sure of with Melo, Williams, JJJ or even Sullinger), and, most importantly, he provides a means of preserving that $8 mil in salary for use in making the team better.
If by midseason, our young bigs show no signs of being able to contribute to an immediate playoff run, Krstic is on board as a decent veteran bench big or as a financial asset to bring in a better fitting big on a decent sized salary without giving up one of our other veteran assets.
Alternately, if our young bigs are blossoming, Krstic can be overpaid insurance in deep reserve (to be ditched at the end of the year) or financial ballast to cash in our young guy's potential for a better short-term option (Josh Smith?).
I'd prefer a Ray + one of Wilcox or Stiemsma scenario, but I can see this as a solid Plan B.
