Salary relief is rather pointless for this offseason. we don't have the talent to make it worth signing a big FA. Bass becomes an expiring deal next year and Lee/Wallace the following year. the cap money will clear in the next couple of years naturally and we'll be all set to go after a FA when are young players have developed into good players or good trade assets.
One benefit of clearing some salaries immediately would be that it gives us more flexibility to use the trade exception, which can be used to accumulate other assets.
It would also clear out the type of salaries that are killer to rebuilders: sizable, multi-year deals, and also clear up positional overloads at SG and PF to make room for the younger, better studs.
And I'd love first dibs at Okafor in the offseason, but having Okafor and Hump both expire (along with Brooks) creates options for keeping Crawford and Bradley on fair deals without running up the cap hit.
Those are two good players, but they really are expendable, and moving on could speed things up. The players they're supposed to be around aren't here any more either, after all.
