looking at the saints record....they might even be more inconstant than the Bills. Looks like they have the Bucs number though.
they beat the bucs then go on a 5 game losing streak...in time to beat up on the gets and shut out old man brady.
you could also say that when the bills are playing above their opponent they play well and when they arent they dont play well.
or it could mean the bills are mentally soft when games get tighter...
