Couple of interesting things I saw about the schedule on Twitter:
Bears vs. Vikings on MNF, week 12 sounds great. However, the NFL is now doing flex scheduling for MNF starting in....week 12. So very possible the Bears might be shut out of MNF for the entire season if they are flexed out
The league almost chose Bears/Chiefs for the opening game but decided the Lions were a slightly better fit due to their strong finish to the season. Apparently that game was moved around quite a bit, from being pegged as the Germany game, to week 1, to week 7 before it settled in week 3.
