I was watching Amazon's "All or Nothing" series, specifically the one about the New Zealand Rugby team aka the "All Blacks" Since the international rugby league is spread across a wide variety of countries and time zones (e.g. Australia/NZ, South Africa and Argentina), it was fascinating to see that the NZ team will send players out ahead of time to acclimate to the time zone. They will also do this even if it means they will play short handed. For example, if they are playing a series with Argentina, they will have players stay in Argentina through most of the series and not physically play in New Zealand till the end of the series. I always wondered how they quantified the benefit or if it was just a "makes sense to do that" style decision.
