Bast is a 2016-17 recruit.
Alec Rauhauser who is still uncommitted is 3rd in scoring among defensemen in the USHL.
Danys Chartrand has to come in next year because he's 21.
Between Wolanin, Shaw, and Evers coming in next year will depend on if someone leaves early. One of those three is going to come in next season unless the coaches add a defensemen late in the year.
I wouldn't be surprised if Murphy and Sanderson are told there will be no room for them next year, with both Matthews and Tkachuk still uncommitted even with them both possibly headed to the WHL (Matthews) and OHL (Tkachuk).
I almost forgot if non of the goalies leave Tomek takes up a forward or Defensemens spot on the roster.
