In theory you an start the season that way, but if a player gets injured and is going to miss less then 10 games or 24 days they can't be put on ltir and still count against the cap, you still need a cushion for recalling players that's why teams usually carry 22-23 on the roster. An injured player can't be assigned to the minors to so waiving/assigning them to the taxi squad won't be allowed to make the space.

25k under the cap with no 13th forward or 7th D.

This is just as of now. My guess is there will be another move.

They might have to try waiving killhorn sure there are teams that would like to add him but aren't on his list of allowed teams.
