that's the biggest piece of i've read in a while.
what's the point of trading tony and manu in order to have young players to develop ? what's the point in that case to keep Tim knowing that would mean without a doubt NO MORE LES since he retires ?
If you think this team even with Tim, can't win another le, then you go in total rebuilding mode and trade Tim.
If you want to win another le with Tim, which is the best thing to do IMO, then you can trade anyone on this team, ANYONE, but not for young players to develop. that makes no sense. And

at trading TP for Devin Harris. not only Tim would be mad to see TP going for a vastly inferior player for his last years, but that doesn't even fit to the idea of the writter to get younger players (Harris is 9 months younger than TP).
