From my viewings of both DU and UW, I would have put Wiercioch as at least the 3rd best dman if he would have been with UW.
McBain and McDonagh, and then Wiercioch. Goloubef, Smith, and Gardiner did not impress me nearly as much as Wiercioch.
It looks like UW's 6th dman rotated between Springer, Little, and Johnson, who combined for a total of 8 points. I would have thought delaying Springer or Little to bring in Wiercioch would have made for an amazing d-corps (more amazing than it already was, at least).
Just my opinion. I understand that things sometimes don't work out between players and teams, but IMO that was a huge loss for UW after watching how well he did this season at DU.
