A couple of situations that call for minor penalties in the rulebook become penalty shots if they are committed when there is "insufficient playing time" to serve them (applies to regulation and overtime). For example, one situation is a defending player displacing the goal frame intentionally; from the 2017-2018 Rulebook, Rule 63.5, Penalty Shot:
If by reason of insufficient time in the regular playing time or by reason of penalties already imposed, the minor penalty assessed to a player for deliberately displacing his own goal post cannot be served in its entirety within the regular playing time of the game or at any time in overtime, a penalty shot shall be awarded against the offending team
Does this mean that 1:59 or less must be remaining in regulation for a minor penalty to become a penalty shot? Technically, the rule doesn't even mention two minutes; it mentions "insufficient playing time." Does this mean if two minutes remain exactly, the minor penalty can be served in its entirety?
