Let’s say a playoff series is best of seven, but one team win four straight games. The final three games are canceled with as little as a day’s notice. A stadium or arena probably sits empty that day, and all the people who were hired to staff it, don’t. TV and radio station (and their advertisers) also lose a big market.
Who loses the most money from this? The ticket holders? The players? The team owners? The stadium owners? The displaced workers? Advertisers? TV stations?
It’s actually amazing there are ever sweeps given all the vested interests.
