They'll probably bring in Chartrand, Wolanin and Shaw on defense. This will fill the loss of Mattson, Panzarella, and Schmaltz. (LaDue another flight risk where Evers or Peski are available)
I hope Caggiula stays and they add another two forwards for next year's class and bring in Gersich, Wilkie, and Gardner. The others seem to need further development.
