I am not sure what day Wooden roll over happened, but if it was Sunday, that is the same day that Rupp rolled over. If they hold Knight until Sunday .. then the worlds start out equally spaced by 7 days.
I know that Knight is a '2 a day' world and the others are not, but it seems they want some spacing.
Or it might not be that at all .. but that seemed to the reason for Rupp.
