Which NFL Teams are Undefeated in the 2021 Season? Only 2 Remain Perfect at 4-0

Two NFL teams are still perfect at 4-0 this season, and they are the Buffalo Bills and the Arizona Cardinals. The Bills’ success can be attributed to their quarterback, Josh Allen, who has been excelling with a short passing game that has been critical to their victories. Despite not being as effective in the downfield passing game, Allen’s patience and skill underneath have been key.

Additionally, Buffalo Bills head coach Sean McDermott has been impressed by the rookie Saints coach Kellen Moore, even though the Saints have started 0-3. McDermott recognizes the hard work and effort that Moore has instilled in his team, despite their winless start.

Leading up to their game against the Saints, Sal Maiorana and Adam Benigni have emphasized the importance for the Bills to stay focused, especially when facing an inferior opponent like the winless New Orleans team. They stress the need to maintain their concentration and not overlook their opponent.

The Bills have acknowledged that their third-down defense needs improvement, as it has been a struggle in some of their victories. Taron Johnson, a key player on the Bills’ defense, recognizes the shortcomings and the team is working to address this issue moving forward.

As both the Bills and the Cardinals look to continue their undefeated streaks, fans of both teams are eagerly anticipating their next games to see if they can remain perfect in the season.
