The Buffalo Bills' defense ranks 28th in points allowed and 22nd in yards allowed throgh 11 games.
The Bills had way too many mental mistakes in the 28-24 loss to the New York Jets last week.
"Last week we had, I believe it was 20-plus mental errors," said Bills safety George Wilson. "Any time you're making that many mistakes, you’re helping your opponents, and it's tough to overcome those mistakes and get victories."
The Bills' defense was on the field for 58 plays against the Jets. Obviously, there could be more than one mental mistake on any given play.
