Boston has approximately $34m, with an additional $4m should Bass opt out. They are committed to Rondo and Pierce, but Garnett and Allen are FAs this offseason. Do not be surprised if they make a run at DWill and Dwight. To do so, they could move Rondo and Bass to a team with cap space (Portland), but I do not think they would amnesty Pierce. This would give them space for two max deals, which could be followed up with resigning Garnett and Allen
