The Buffalo Bills beat the New Orleans Saints and move to 4-0 on the season, but the defense is still clearly the primary issue. At the end of the day, very rarely does an NFL team have a win where nothing goes wrong.
There is simply too much parity in this league for that to happen, and with 53 men on an active roster, there are bound to be positional weaknesses. Through four games, the Bills are 4-0 and have taken are of business each week thus far. Reigning MVP Josh Allen has been great this year, and the offense is working well.
