They haven’t done this with any other prospect, so does this mean they have revealed their pick? I may be reading into things, but it does make sense. Alex Turcotte has been linked to the Blackhawks in multiple mock drafts by various NHL analysts. He also fills a position of need at center.
As of right now, Turcotte has committed to playing hockey for the University of Wisconsin next season, but players have gone back on their commitments before. This actually happened as recently as last season. Brady Tkachuk was committed to playing for Boston University, but opted to play for the Ottawa Senators in 2018-19.
