That's IMO the one remaining bit of lineup makeover the C's have to do with their current personnel.
Will they? I suspect with Rondo out such a move would be delayed a bit longer, since Doc's used to Pierce sometimes doing more ball handling. Also, if Danny were to be considering trading him, they might not want to bench him in a lead up to that.
But I think it will be good and important to see how having the four young guys and KG starting works for a few months, to help in evaluating who is part of the longer-term answer.
