Right now Calle Jarnkrok and Teemu Pulkkinen are in their 2nd year of development since their draft date and are putting up even better numbers than Datsyuk or Zetterberg did at their age. The Datsyuk and Zetterberg didn't really come out of nowhere either each played 3 years at home developing after they were drafted so the Wings had plenty of time to get a look at them
Then you have prospects like Tverdon, Jurco, Ouellet, Sproul and Mrazek who are all having fantastic seasons in the CHL giving the Wings one of their deepest prospect pools they've had in decades.
As far as that poll, it was done by CBC and was voted on by the players you can see it here. Its also interesting to note how many categories Datsyuk was selected in, on top of that Parise has already said he is his favorite player in the league. If he hits Free Agency Detroit will certainly be one of the favorites to land him.
