Saturdays ended later because they started later, Sundays earlier cuz they started earlier. They could still stagger games better so you don't have 2.5 games completed as standalone games, especially factoring potential blowouts. Leave the earlier game as a standalone but start staggering them shyts after that.On the weekdays.
I distinctly remember the round of 32 and the regional finals being over by the time 60 Minutes came on.
