As the Buffalo Bills arrive in London for their seventh and final game before their bye week, they are part of an unusually small middle class of teams in the NFL.
The 3-3 Bills are joined by only the Colts as teams with an even record through six games, the surprising result of a season that has seen five teams remain unbeaten through Week 6, the most since the NFL-AFL merger in 1970.
There are 19 teams with losing records, although the Eagles have a chance to join the small club of 3-3 teams if they defeat the Giants on Monday night.
