It was a great week for the public as every single favourite was victorious with the exception of the Buffalo Bills who fell in the final minute as a 3.5 point home favourite. This came one week after only 2 teams that were laying chalk were able to cover the number in week 6. Lets take a look at some of the key match ups this week.
