Scoring is a weakness today, but isn't going to be a weakness in the coming years. The Stars have drafted nothing but talented forwards who will make impacts in their early 20s. The sense of trading Hintz for a D is that Hintz is that his peak might have been this season/last season, and signing him to a long-term contract (like Benn and Seguin) could leave this team once again paying a player for their past performance, not their future performance.
RHD is also not an organizational strength. Hakanpaa is the only one in the organization with a meaningful NHL future.
First of all, do you remember when Nill miraculously got Seguin and Spezza? Miraculously, because it is said that no. 1 centers almost never are traded, and for good reason.....it's among the hardest and most important spots on a roster to fill. So the Stars finally draft one (the best option possible) and the am GM's want to trade him because he MIGHT NOT be as good down the line, or MIGHT get hurt, or MIGHT want a lot of money?
So, yeah there would be a line to get into to trade for him, and he might yield a haul. If it is like the Johansen for Seth Jones trade, yes, we could get a D. Would that guy take a low Klingberg contract? Would he possibly get injured or decline? The problem with your, and most fan scenarios is that the unnamed player we will surely get will be absolutely perfect in every respect, which rarely happens in any league, NHL included.
Or do we trade quality for quantity, i.e. a bunch of lesser players to make sure we don't have to pay a lot in contracts? And typically, the team that trades for the best player wins the trade, which isn't likely to happen with a bunch of average players. The Stars don't need any more of those, they need some top end scorers, and if they trade Hintz, they need to get two back os similar quality to improve, no?
Or we trade him for a bunch of picks, meaning that while Johnston, Harley, etc. could come up and perhaps catch the end of Hintz's top play period, we delay the onslaught of young talent either further until they get here in a scenario like the current Benn and Seguin, i.e. past their prime, scenario, being more likely to be mediocre longer, rather than taking advantage of the good players we do have. And typically, the team that trades for the best player wins the trade, which isn't likely to happen with a bunch of draft picks.
Obviously we won't be able to run the many hypotheticals, but based on history, I am confident that trading Hintz wouldn't work out too well for us.
And, true hockey trades are pretty few and far between these days, but are really based on cap and other needs. As Bob Gainey once told me, good players are only offered around if they are hurt (maybe on Hintz, but doubtful) or have contract or attitude problems. As an RFA, I doubt Hintz will be a huge contract problem, and we have no indications that he has attitude problems. So, I see no reason to shop Hintz for a hard to identify player who you have yet to name, because, well, fans never do.
By this logic, we should be trading Otter right now while his value is the highest, no?
