FWIW it may be to make travel arramgements for teams. My wife and I booked a room in Boston in October years ago to see the Head of the Charles crew races. Turned out the Red Sox reached the World Series that year against the SL Cards. Now Head of the Charles draws teams from across the country. Rowers from high schools, colleges, clubs, masters all compete over 3-4 days. My son was coaching a HS girls boat from Everett Washington to give you some idea. Anyway, ALL the hotel rooms within 25 miles of Beantown were absolutely full. Not even a Hotel 8 was available. The Cards wound up getting rooms WAY outside of town. It was amusing to read how pissed the Cards were, because they were extremely vocal about the situation.
Anyway, though I'd like to see reseeding after each round of the playoffs, teams have their own take on the issue.
