Unfortunately, Green as Worthy, isn't enough for this current crew.
As for the HoF small forward, the reason why I'd picked King is that he's the only guy who could basically do it alone. With only Bill Cartwright (pre-injury) by his side, he took the Celts a full 7 games in the 84 ECF. And that was a championship Larry Bird team.
Now, imagine him and Rondo (with Stockton's shooting) on this squad of ours. Basically, all we'll need to add are the complimentary role players: Tony Allen (in-your-face wing defender), J Posey (No fear of the Big Game, jack-of-all-trades defender/shooter), and K Perkins (Enforcer, thug down low) and we can contend.
