Correct but there is a point where they get too over-riped in the minors and need to come up to the majors.
-Not having a post-Lidstrom sucession plan in place.
-Franzen vs. Hossa
-Uwe Krupp debacle.
-Not getting more Defensive Depth when you knew Lidstrom was going to retire in a few years.
-The Jimmy Carson Trade.
Border Line (I couldn't decide if they should go)
-Robert Lang trade. There are a lot of factors that went to this one including A. The Fact he was leading the league in scoring at the time B. The 2009 Cap mess etc.
You listed a lot there, and some of them go further back and are good examples. I think the Krupp situation is a good example of a "mistake", at least in retrospect. Of course, poaching a 6'6" right-handed defenseman from your bitter rival probably seemed like a great idea at the time. He had missed a good amount of time previously due to injury, but predicting the whole thing with the dog sledding while he was supposed to be rehabbing (and the grievance) would have been hard to foresee. http://blog.mlive.co...wings_no_9.html
But the "failing to have a Lidstrom succession plan" one, which you are far from the only person to suggest, just makes me chuckle because you CAN'T find another Lidstrom, and it's not like having 2 "good" defenseman is the same as having 1 "elite" one that logs 25 minutes a game and virtually never screws up (not to mention quarterbacking the power play).
Plus, unless you're talking about Chris Pronger, Scott Niedermayer, or Zdeno Chara, it's really pretty hard to find examples of defenseman that are so impactful you could basically plug them into any team and have an instant defensive powerhouse. No better example of that right now than what is happening with Ryan Suter in Minnesota. I was among the people who really wanted him here, but it turns out that when your partner is Tom Gilbert instead of Shea Weber, suddenly your defense doesn't look as stellar.
The problem the Wings had with replacing the defensive corps is the same they have all over the team. Other than Suter, there really was no "free agency" fix for a top-tier defenseman in the offseason. You could argue that Holland should have traded for one, but since the Red Wings rarely have draft picks above the 20th pick, it's not like the Red Wings have elite caliber prospects like a Hodgson or Kassian that you see swapped around for considerable value before their careers have taken off (in that case, they were swapped for each other). If the Wings are lucky enough to develop the next Datsyuk or Zetterberg, that won't be apparent to the league until they're already proven pros, at which point we'd probably want to keep that player.
And even though the Wings seem to trade their 1st rounder basically every other year, it's almost a guaranteed low first rounder, so the returns are more like Kyle Quincey than Jonas Brodin or Victor Hedman.
Nobody doubts that the defense is a problem, but to call it a "mistake" seems a bit unfair, or unrealistic.
