To your point, Brock Schultz and Cooper Simpson are definitely locks. Between O’Niell, Ashton Schultz, and Pilgrim, O’Niell will very likely be the chosen because of his size, skating, and compete level. He’s a guy that you can plug and play in the bottom 6 next season and potentially play PK as well. There is a risk of losing the other two but other programs might want them back in juniors as well. Pilgrim probably will play college next year, here or elsewhere.
I would guess if nobody leaves early, they will make room to get another open spot. Adding a player from the CHL and one experienced player from the portal would be ideal. I see them adding at least one player that can play up in the lineup next year.
