Wisconsin's scheduling agreement with North Dakota has always been planned to start with the 2014 season. So the two teams will take one year off from playing each other (I don't know why).
Wisconsin will host North Dakota, Michigan Tech, and Boston University in 2014-15. They will also play single games @ Denver and @ CC.
In 2015-16, UW goes back to Grand Forks, and plays singles at BU/BC. They host Denver.
In 2016-17, UW hosts Boston College and North Dakota, and I would assume play singles at CC and Denver.
See the trend?
In between you're going to see a lot of teams mixed in, but if you see North Dakota, BU/BC, Denver, CC on your schedule every year in addition to the Big Ten schedule...it's hard not to be happy.
