While I like the concept, I don't like the personnel. Why not go for broke and sell them on an expiring package to go after a free agent next year.
Boston sends Ray, Baby, Tony and Scal
Washington sends Jamison, Butler and Foye
Is this trade unable to happen until Dec 15th? Yes, but that is just 3 weeks away.
Is this trade heavily favored in talent coming Boston's way? Yes, but it also provides Washington with the chance of possibly signing 2 big name free agents next off season to add to Arenas if the renounce everyone or 1 big name free agent while resigning Haywood or Allen.
Is Boston taking a chance adding a ton of salary beyond this year? Yes but these are the rosters for this year and next:
2009-10
Rondo/House/Hudson
Foye/Daniels/Giddens
Pierce/Butler/Walker
KG/Jamison/Williams
Perk/Sheed salary = same as it is now about $84 million
2010-11
Rondo/Hudson
Foye/
Pierce/Butler
KG/Jamison
Perk/Sheed salary = $90 million with the MLE and vet mins available or less if Pierce opts out and renegotiates at lower than $22 milliom per.
