Something new that was implemented in the NFL’s schedule over the last few years was the addition of a flexible schedule during later weeks in the season. Essentially, five games would be played on either Saturday or Sunday and later in the season after the college football regular season is over, a determination would be made on which three of those five would be nationally televised on Saturday. It allows the NFL and networks to choose sexy matchups to feature instead of being stuck with late-season duds.
This year, the flex is happening in Week 16 and for the second straight year Buffalo has that opportunity.
