We lose only two seniors, one of whom never played and the other of whom played sparingly. Obviously, we could very well lose Bjork and Petersen to the NHL, both of whom will be very difficult to replace. Likewise, Connor Hurley's status is still in question.
The other major change, of course, is the switch to the Big Ten, which is smaller but with fewer bottom feeders. I think we've got a reasonable shot to contend for the conference title right off the bat if we get solid goaltending from Morris or perhaps Nick Sanford.
