If Pierce and KG retire it will take more than Rondo and Green to make this team a destination again. Yes you might be able to get Josh Smith; but that is still not a core group with the kind of leadership that you need to win a championship.
Should Danny try to cobble something together with Free Agents or does he need to shake things up? Are there good enough free agents out there that he can just let KG and PP retire or is trading KG and PP together the only way that he can rebuild?
