I think last season was basically a year of playing things out. Let Rondo rehab, let the coach feel out the league, see how the players under contract look and get a high pick.
This season it will be important to see what level a healthy Rondo is (star or super star?) that will dictate his value on the trade and FA market. To me the second thing will be establishing if Sully and or KO are pieces for the future (will either have the ceiling as fringe all star and cement a starting role?), they need to both play mostly the 4 and see how things play out. Third will be determining what they have in Smart, is he good enough to make Rondo less valuable to this team?
I expect these goal will lead to more winning. While still a lottery team I think we will see many close hard fought games where the team loses do to personnel holes (floor spacing/rim protection) not effort (and to a lesser extend talent).
