I would think that Cichy will come in regardless of who leaves. Same with Toews, Gregoire, Hextall, Lamoureux, Eidsness, and Blood.
The players that would more depend on who leaves or who is more ready would be Gleason, Finehage, MacWilliam, and Bruneteau.
Bruneteau was slated to come in for 2008, but has struggled to get back in the lineup after his concussion, so I wouldn't be surprised to see him play another year in the USHL.
