Taken from Rotoworld, per WGR:
" The Buffalo defense has allowed seven plays of 50 yards or more this season.
That total ties the Bills with the Oakland Raiders for most 50 yard plays allowed in 2016. The Bills currently sit 13th among NFL defenses in pass defense, but big plays have done damage to this group. Buffalo will need to look for a solution to the big play troubles during their bye, as they will return to face A.J. Green, Allen Robinson, Amari Cooper, and Antonio Brown in consecutive weeks. Nov 11 - 4:27 PM "
Don't know what's scarier, the WR we face with big play potential or the fact they have Mario Williams as the face of the Bills D 😬
