I don't see much point in nitpicking every single move and draft pick Yzerman has ever made. You can make every GM look bad that way. I don't think Yzerman is a particularly error-prone GM, and he's been solid at the draft.
The bigger problem with Yzerman is the moves he hasn't made. There's a fine line between being patient and being passive, and Yzerman has definitely crossed it.
For all the problems being a bad team brings, bad teams also have advantages that contenders don't have. They have open roster spots, cap space (if the owner's willing to spend, and Detroit's is) and low expectations. They have plenty of opportunities to make moves and take low-risk gambles. Trades for talented players with bad contracts who could use a change of scenery. Acquire waiver wire guys, and guys with potential similarly buried on good teams' depth chart. Offer sheets (it's not like Doug Armstrong is the only guy who can use those). There are many ways to improve your roster beyond the draft and free agency, and those moves can yield just as much value (if not more) than a good 1st round pick.
Yzerman just hasn't done a lot of that in Detroit, for a guy who's been on the job nearly 7 years. As far as I can tell, the only long-term non-draft piece he's added to this roster is Debrincat. And that was a really good move, but over such a long period you'd expect a little more.
Regardless, after 7 years, there's no deflecting the team's results aways from Yzerman. Some select Wings fans are very keen on crediting every good outcome to Yzerman, and every problem they have to Lalonde/Holland/Draper/scouts. That's disingenuous. The rebuild isn't taking a while just because of Ken Holland; it's taking a while because Yzerman is taking a slow and safe approach to it. And I'm sure it'll yield a good team eventually, in 1/2/3 years. Though I don't think this roster's upside is amazing: ASP, Cossa, Danielson and MBN won't make that team into a contender.
Ultimately, at least in Detroit, Yzerman has been a thoroughly average GM, doing a really unremarkable rebuild. A rebuild that probably doesn't warrant a 140-page thread.
