Bill Daly states that with the way accrual accounting works, a team can take on an expensive contract toward the end of the season and not have the full cap hit. But if a $1 million contract suddenly counts as $5 million at the start of the playoffs, and that player can't be used because of it,
that doesn't seem fair since the teams followed the rules, which is why it would be a challenge trying to add a playoff salary cap.
