A couple of points are coming out of this. One is that we have done a pretty good job of building the team through the draft (Tatum, Brown, Smart, Williams, Williams, Langford, Nesmith, Pritchard). I think Rollie is saying stay with this. The more you can build through the draft, the better, but no team that contends for a title is going to build solely through the draft. We have had worse luck with the FAs/major trades we have done (Kyrie, Horford, Hayward, Walker) but most teams need to add a player or two this way to get over the top.
As to trading Langford and Nesmith, certainly no need to trade them just to trade them but I am open to trading one or both if it improves the team. I like both players and hope we don't trade them, it all depends on the deal. I would trade one or both for an upgrade at PF for example.
