I think Rondo is the Pierce from 2005-2007 that this team needs to keep like they kept Pierce. Rondo isn't THE cornerstone guy(KG and his defense was) but he is too valuable to trade away hoping to get worse to possibly get one of those guys in the draft.
As the others develop, Ainge will need to judge who to trade, like he did with Jefferson, Green, Telfair and Gomes. And he will need to decide which young players to keep like he did with Perkins, Rondo and Tony Allen.
As long as Humphries and Wallace don't have bounce back years and/or are played a lot or Sully, Green, Bradley and Olynyk suddenly develop extremely fast into excellent players, this extremely young team should be in the lottery next year, though not that low.
In a perfect storm, Rondo could once again be an All-Star leading the league in assist and steals and scoring 15-17 PPG. Bradley could be one of the better D and 3 guys in the league and a 1st team All-Defense player, Olynyk could be a ROY candidate because he can score and those voters love offense. Sully could turn into a double double machine down low with great defense and green could become a 23 PPG scorer and defensive stopper at the wing.
And if that happens, this team could be in the playoffs next year.
And.....so much for the tanking.
