What's crazy to me is the shift from always having afternoon games on weekends to prime time games. To be honest I never understood the love for afternoon games.
Part of it is right now the league is off schedule so the daytime slots are filled. The other part is sports programming has become more important the last decade (and last half decade) opening up the night spots pre-final. Also, NBC learned that early in the playoff putting a live game in primetime allowed them to also put SNL live across all time zones increasing their profits over reruns (although SNL is now done for the season).
The prime time over the air game games pre-Final are probably done this year. I’m going to imagine the NBA gets those slots over the NHL on ABC and Turner is cable only. That means the return of later round playoff games in the afternoon.
