This is the deal I would do:
Rondo, Green, Faverani
for
Lin, Asik, T. Jones, $3M, two 1st rounders
Celtics save around $5M this year, spend $10M extra next year with the funky contracts, then save on the last year of Green's deal. They get two more 1st rounders and another cheap, young talent in Jones. Lin and Asik can both be either kept or dealt as big expiring deals next year, and Jones will be cheap for another two years.
New lineup:
Lin
Bradley
Jones
Sullinger
Asik
+ more accelerated cap space, two more 1st round picks
