Better question would be how we could fill out the roster if KG and Pierce both retire. Some of those contracts for mediocre talent might be a little annoying.
Jeff Green making 9 mil. Bass making 6.5 mil. Lee and Terry each making 5 mil. Rondo making 12 mil... those are the bigger contracts.
We'd maybe have enough money to offer one max contract, but sadly not two max contracts. Kind of a shame, because if we didn't have Terry, Bass and Lee clogging up money, we could theoretically offer Josh Smith and Dwight Howard max deals to come play with Rondo.
I don't think either J-Smoove or Howard is coming here regardless.
No, I think the cap-clearing plan would be to try to trade Rondo along with a couple of the guys you mentioned (e.g. Terry/Lee and Bass) for younger talent. Perhaps to move up in the draft if Danny really likes somebody in the Top 5. It's a weak draft so Rondo could get a top 5 pick from a team desperate for a sure thing.
