It could also imply that cuts have already been made. They may have not made official cuts but the coaching staff may have made decisions on a number of players. For example, here are the non roster players that are not listed as part of this group:
Jeremy Davies, Stephen Halliday, Hayden Hodgson, Garrett Pilon, Maxence Guenette, Tomas Hamara, Djibril Toure, Wyatt Bongiovani, Jake Chiasson, Philippe Daost, Oskar Pettersson, Jamieson Rees, Keean Washkurak, Michael Simpson
Of that list only Halliday and Guenette would be the somewhat surprising cuts. Even then, Travis Green mentioned that after the 4 day mark of camp there is a big drop off where bubble players start getting fatigued. I thought Halliday was showing some signs of that so if he does get cut then it won't be that big of a surprise as he is just getting his feet wet in the pro game.
