To me its irrelevant as long as every game is starting at 7:30. I'm still watching NYCFC instead of whatever "premium" game they're offering.
Also there's no reason they can't use all their technology for every game, other than cost. MLS continues to run its broadcasts on the cheap and are using these "spotlight" games as a cop-out.
When we move to the winter schedule, MLS has a glorious opportunity to piggyback weekends with the Premier League. On Saturdays, after the 12:30 EPL game we should have games at 3, 5:30, 7:30, and 10. On Sundays after the 11:30am game is over, we should have games at 2pm, 5pm, 7:30pm, and 10pm. Give people a reason to sit in front of the TV all day and watch soccer.
