I suspect that the fixed times are intended to create predictability and uniformity for both the viewing audience and the stadium audience. My guess is that there are some in team FOs that are disappointed to lose flexibility to set times based on local market factors, such as some teams that tended to schedule daytime games in the February/March timeframe before the weather warms up. With the fixed times, the TV audience knows that almost everything is going to be within a five-hour block on Saturday nights, and the Season Pass programmers are going to bookend that with 30-minute pre and post shows. Stadium attendees get a very predictable schedule as well, though the Fox games create some variety there. What they aren't going to do is stagger games to appeal to a viewer who wants to watch MLS 10-12 hours straight. The number of people who want to do that must be vanishingly small, and they shouldn't outweigh the more typical viewers and the in-person considerations. If you want to watch that much MLS, watch replays. As it is, you can get 7 hours with a Fox game and the 5-hour block.
