Again, rebuilding teams don't trade draft capital unless a young Debrincat falls in your lap. Drouin was a former 3rd overall pick. Yzerman isn't trading Raymond, he's not underperforming.
You know that trading is not restricted to top-5 picks, right? If Yzerman has the incredible trading skills you implied, well there's no shortage of players or prospects on the Wings that should be jettisoned for a good return.
Show me a rebuild that took 6 years or less that didn't have a top 3 pick.
Of course the question is a bit of a trap, since most teams who require a rebuild are likely to obtain a 3rd overall pick by chance, even if that top-3 pick doesn't do much. But despite that, it still happened.
The Cup-winning Ducks were built without picking top-3 (technically they picked Ryan at 2 in 05, but he hadn't made the NHL when they won). Similarly, the post-lockout Flyers bottomed out, and bounced back before their 2nd overall had even left college. The Preds sank in the early 2010s and climbed back out to make the Finals without picking higher than 4th. The late 2010s Isles actually bounced back when their sole top-3 pick left in free agency, and made multiple deep runs. Arguably the post-lockout Sharks too, depending on when you feel they were "built"; they did not pick top-3 after Brad Stuart in 98. The recent Wild too, if you believe in their strong start, unless you feel merely being mediocre doesn't qualify you for a rebuild. And I'm sure I'm missing many.
The fact Yzerman selected a top 2 player (and Calder winner) with the 6th pick in 2019 and a top 3 player (Calder runner up) in the 2020 draft with his 4th pick is HUGE. That's good drafting. Scanning through the 2019, 2020 proves to be weak drafts. Not one gamebreakers were produced outside the 1st round. That's Yzerman's fault how? /facepalm
Your expectations for drafting are damn low. Yes those two picks were certainly good picks, but hitting on your high pick and whiffing on the 10 other picks is not a sign of great drafting.
I can count between 10 and 15 post-1st round players from the 2019 draft alone that would improve the Wings roster. Many are already pretty good players: Vlasic, Protas, Macelli, Kochetkov, Dorofeyev, Voronkov...
2020 looks a bit weaker in late rounds, but there were still good players found in the 2nd and 3rd. Faber, Peterka, Evangelista, Laferriere...
If those drafts were so weak, how do you explain the fact that all the other bad teams (Anaheim, Buffalo, NY, LA, NJ, Chicago, Ottawa, Arizona...) found NHL players outside the top-10, while Detroit didn't despite having more picks than anyone else?
Are you going to demand Yzerman cures cancer and solves world hunger for his next civil duty?
I won't, but I'm a bit worried you might expect it. In roughly 20 years of lurking on those boards, I have never seen a fan with as much blind faith in a team executive as you.
