Just my guess, but with basically 4 spots to fill (since they seem to like to keep a spot open for needs/opportunities), I think they end up with:
Bonner
+ a veteran PG who could be relied upon to step in and start for a stretch if Parker is injured (someone along the spectrum between a Terry Porter-type (a former all-star chasing a ring, but who can still play) and a Jacque Vaughn-type (an under-skilled and under-sized guy who competes and generally makes good decisions)). I tend to think they'd prefer some length here, with an eye towards using Patty more as a shooter in a lot of situations.
+a project-type big with ,
+a younger guy with some promise as a 3-and-D wing unless they figure out a way to get Caron Butler.
