I agree we need a star, and I dont think FA is going to yield one for this team. I think this star is going to have to come from the draft and this will lead to the end of the Rondo era in boston.
My personal views / predictions of the youth currently on the roster,
Smart, a very high end frindge all star role player. He will be an all defensive player who gets around 14-16pts per but never dominates on offense.
Sully, I have been really happy with his growth as a player and the key now is bringing his conditioning up. A better conditioned Sully (10lbs lighter) is an near 20pt 10rb randolph type lower end allstar. Never a star but a good 2nd/3rd option.
AB, still has alot of development ahead of him. I like him as a 5th starter on a contender 4th guy on a playoff team.
KO, super sub. His D will never make him a great starter. I like him as a high usage backup 4/5 who is the focal point of 2nd unit offense and finishes out games where scoring is needed.
Young, wild card. Wouldn't shock me to see him become JR. Smith minus the attitude issues. Has great potential to be a 20+ pt wing scorer who isn't a liability on D.
