This is a lot of hindsight rationalization of objectively bad decisions. We have to view things in the order they actually happened.
First, Sakic new the Avs #1 need was defense, and when the top Dman in two drafts (Larsson, Jones) fall into his lap, he goes with the flashier Landeskog and MacKinnon.
Then, he has to deal with the fallout of those two decisions, which was a much, much more difficult re-signing of ROR and Statsny, both of which saw an organization that was putting all their eggs in MacKinnon's basket. And losing Statsny gave more leverage to ROR. Sakic was offended by both their opening offers and the overall market, and went on a PR campaign about how the team isn't going to overpay to keep guys that part of the teams core.
Finally, Sakic fails to smooth out any of the rest of the roster. Blueline still can't play defense. MacKinnon is better at wing. Center depth went from top of the league to bottom.
Last I checked the old management botched the entire ROR contract negotiations before he was made GM and before Mack was involved making it doubtful he was going to take a reasonable contract. He wants to play Center so if we already had Duchene (who prefers C) and Stas signed in your scenario , where is ROR going to end up playing and for how much? Stas was taking no less than 6.5 and O'Reilly wouldn't either especially to play at wing. None of this is hindsight, you just can't keep together a group like that for long in todays NHL without being thin in other areas.
I have said it before, but if they hadn't been doing so good that year when Stastnys contract was up, we most likely would have seen him traded at the deadline for a decent return. Nobody expected them to be winning like they were, and as a fan it sucks having to watch that Jekyll and Hyde team every year.
At the time they thought those players would be better than taking the D with such a high pick. When you are that high up you don't just take the position you need. Avs weren't the only team either that felt there were better forward options than Jones.
Who is to say that the Avs drafting Jones and Larsson makes them a good team now or better off. They have developed like one good D man in 10 years (Barrie) . Nobody knows how those players/ the team would be like now and we will never know. This is the first time I have heard someone call Landeskog a flashy pick though lol.
Basically you think the Avs should draft Liljgren if they get the #1 regardless of who is actually the best player in their scouting departments eyes.
At the end of the day its a lot of assumptions and a lot of perfect alternate universes on how things would be differently for the better. Nobody knows if they had drafted Jones over Mack that they would have been able to keep Stas and/or ROR. For all we know if they drafted both D instead they would be left with a forward group of Duchene ROR and a bunch of overpaid FA forwards on bad contracts for 5+ years (kinda like now but at least its almost over haha)
All I know is I don't want to see Landy or Duchene traded, but if for once in the past 14 years we could have a good D group from those trades with a few solid forwards like Mack, Jost, Rantanen, 20171st I am all for it. Whatever formula they have been using since there last cup hasn't worked and I just want a different team outlook as long as it starts producing wins and good hockey. So if that is with or without Sakic Idc, just stick to a plan and go through with it for once with no shortcuts like in the past.
