You’re now the Mavs’ GM. What are you going to build?

I suppose its possible that they age gracefully enough that the Mavs can get something for them down the road on different contracts (although I can't imagine it will be the haul the Celtics got).  My main point was that if they are aging that gracefully I think the Mavs will still be in window one during the length of the current contracts.  Who know what will happen after that (they might not even re-sign here).

Danny Ainge and the Celtics traded the veterans just as they were about to start really 'aging-out' but their value was still perceived star like by at least 1 NBA front office.  Perfect timing.  As you said, I'm not expecting Dallas could pull off that kind of haul but the basic idea is veteran star, still perceived high value by at least 1 trade partner = trade-ability. 

My main point was that if they are aging that gracefully I think the Mavs will still be in window one during the length of the current contracts. 

Got that.  I get that if they're playing well you don't believe Nico would trade one of the veteran stars.  My point is simply that the scenario is in play where IF their veteran stars are healthy the Mavs retain the potential of pulling off a trade with them.  

Nico I can't predict.  IF he even retains his role as GM the next few years this is the guy that traded Luka Doncic.  I don't know that he wouldn't trade one of his favorites if he thought it could improve the roster balance for a window run. Maybe he's not even the one making decision at that point and the Mavs decide to age-down around Cooper ala Phoenix Durant trade. 

Main point, it all hinges health of the players but if its good they'll retain optionality.
