Yes I think the same.
And maybe the use of a fixed rotation would be more problematic than "Let the coach decide" or "Free rotation", because in a fixed rotation, players will play more than 35 min in very close games, even if they are exhausted and their performance drop dramatically.
I also think that maybe we could use a roster of 8 in PO, but put one of two player as reservists just in case of exhaustion of starters and bench...
