Lakers roster has so many holes, they need to make a one for many deal, while the Celtics need a many for one deal.
So putting aside the Celtics/Lakers rivalry in my fantasy, assume it is now past Sept. 12 when most of the Nets players can be traded.
How about a Pau/Blake trade for Humphries, Wallace, Crawford, and Melo (or Iverson, regretfully), and whatever other filler (Brooks?) is needed to tempt the Lakers?
With Faverani's outside shooting, the Celts can properly space the floor with Gasol, Faverani, and Green starting, and a 2nd unit with Sullinger and Olynyx joined by either Bass (to play big small forwards) or Bogans (to play quick small forwards). Bass showed some ability to guard Melo in 2013 playoffs and James in 2012 playoffs. Gasol and Olynyx can work the inside post, and Sullinger and Faverani can do some damage there as well. All but Gasol have some outside shooting range.
Except for Wallace, all guaranteed money expiring after 2013, so not much impact for either side, and Lakers better positioned to absorb Wallace's long term salary.
