I largely agree. I somewhat questioned Danny's move to lock up Bass for 3 years. He's a nice player, but even if Sullinger proves too short to be a post threat in the NBA, he could still probably do what Bass does now: pop wide open jumpers from 15 feet out. And he could probably grab more rebounds while doing so.
Still, I think Danny retained him not only to help win now, but also to keep his value for a potential future trade.
And now we have quite a few chips with the likes of Bass, Bradley, Lee, Terry, Green, as well as Sullinger and Melo.
As much as I do like what he's done, I do have some trouble conceiving exactly how we'd pull off a trade to maximize this value. I know you mentioned the possibility to trade Terry now if we wanted, which does sound good to me. The only problem to me then becomes, for what?
Assuming we're healthy, we're likely stacked at the wings with Lee, Bradley, Green, and Pierce. We could probably use an upgrade at the 4/5 spots; however, is anyone going to give us a big man who can make an impact for a 35 going on 36-year-old 6-1 shooting guard?
Still, there are probably ways of pulling things off eventually, so I do overall like what Danny has done.
