The only real flip flopping of players that has been done seems to be this past weekend for WJT. Schack got some playing time that he usually doesn't see, but like the other poster said it wouldn't surprise me to see him out on a little smaller sheet of ice against a more physical team.
There's usually a change between lines it seems like, but players stay pretty similar.
I can almost guarantee that the first line will be Stoa/Schroeder/Barriball, but from there its a crap shoot. 2nd line is usually some combination of Hoeffel/Lucia/Flynn/White/Carman, but who knows.
Guessing the first D line will be Fischer and Ness again, 2nd one Anderson and Fairchild, 3rd one Wehrs and Loftquist.
Also I think the small ice fits the Gophers style well, especially guys like Ness, Fairchild, Schroeder, etc....guys that can really pass the puck quick and accurately. Going to be a great series.
(Oh, and Kangas will give up 2 each night, mark it down)
