Wednesdays have been off limits for the NFL through most of its history. For decades, so was Christmas Day.
The NFL is always looking for opportunity and it found one when Christmas Day fell on a Wednesday this season. The league had four teams play on the Saturday of Week 16 and then switch opponents for Christmas, so they were on the same rest as teams that play on Thursday night after a Sunday game. Netflix paid up to broadcast the games. And that's how we found ourselves with a doubleheader of football on Christmas, on a Wednesday.
