Yep, RSNs show plenty of pre-season. The bottom line is this is a LEAGUE thing, not a cable, DBS issue and not sure why we always argue it here every season.
It's argued every year because of the desire to see FOOTBALL !!! and get the season started.
That said, I'm glad they play some preseason games, I think 4 is plenty, 3 would be sufficient, but I know the teams have to have enough time to evaluate the talent on thier teams....
