And the NFL is not as far from seven days a week as you think. There will be weeks with 4 days of NFL football this season. There will be games played on Sun, Mon, Wed, Thurs, and Sat this year. There will be games played essentially every 2.5 days. You don't see the slow trend of more & more football each season?
The only reason there will be football on a Wednesday, is because that Thursday is taken up by a presidential speech. BS example is BS.
And the season will only have Saturday football ONE week this season...another BS example.
You don't think the league will try to add a 4th full time day to the NFL Network schedule (Wed) at some point? They will never go seven, because the union will never allow Tuesday, but I would bet on four, and I would bet on Fri & Sat games becoming more common once high school & college games end in November.
So we're barely at 3 days/week, and you're already anticipating 4 days/week (we dont know that will happen), and anticipating that 4 days/week will have negative effect on the league (we also dont know that would happen). Lots of worrying on your part for no tangible reason.
Also, 4 days/week is still far from 7 days/week.
