Don't see Rondo as a need when they have Walker at such a low cost. MKG, Vonleh + filler for Green and clipper's first should be something to consider.
Walker, Stephenson, Green, Biyombo, Al could make some noise in the playoffs. All guys are under 30 so they can go for a good run. Vonleh is 2 or 3 years away from helping a playoff team. MKG is too limited a player to help that team too.
Smart, Young, Vonleh would be a great rebuild haul in one year.
