403 – With over 400 yards receiving thus far Stefon Diggs has set a personal best for most receiving yards through the first four games of a season. His previous high in the first quarter of a regular season was 2017 when he had 391 receiving yards. Diggs, who is tied for the league lead in receiving yards with Seattle's DK Metcalf, is on pace for 1,612 receiving yards by season's end.
91% - Much has been made of Buffalo's scoring exploits over the first month of the season. One need look no further than the Bills red zone touchdown percentage. Over the last three games, Buffalo has scored touchdowns on 10 of their last 11 trips inside the opponent's red zone for 91 percent success rate. That's the highest success rate in the league over that stretch. Only three other teams in the league (Seattle, Kansas City, Dallas) are at 80 percent over the last three games.
20 – Josh Allen logged the 20th rushing touchdown of his career in the win on Sunday. With 20 rushing touchdown in his first 32 games Allen has become the second-fastest quarterback to reach 20 rushing TDs in league history. Cam Newton is the only QB to do it in fewer games (27).
2*nd* – Right now this is Josh Allen's most popular rank in the league's passing statistics. He's second in passing yards with 1,326 trailing only Dak Prescott (1,690). He is second in passer rating with a mark of 122.7, behind only Russell Wilson (136.7) and he's second in passing TDs with 12, with again Wilson the only one ahead of him with 16.
82.4% - Since 1990 teams that start the season 4-0 have reached the playoffs more than 82 percent of the time. Taking it a step further, they've gone on to win the division 63.5 percent of the time, and they've won the Super Bowl 14.1 percent of the time.
15.5 – Andre Roberts is the league's punt return leader with a fat average of better than 15 yards per return. His 39-yard punt return in Sunday's win helped to raise his average by more than three yards on the season.
21 – Buffalo's passing attack leads the AFC in pass plays of 20 yards or more this season. The Bills receivers have pulled in a total of 21 passes for gains of 20 yards plus. The only team in the league with more right now is the Dallas Cowboys with 22.
6.8 – The Bills offense is also leading the AFC in yards per play on first down. The 6.8 yards per play on first down ranks fifth in the league as four NFC teams (Atlanta, Green Bay, Minnesota, L.A. Rams) have been even more prolific.
67% - Buffalo's receivers have been a large part of the team's passing success. All their three and four wide sets have made the Bills wideouts the primary contributors to the team's yardage totals. Through the first four games the Bills receivers have accounted for more than two-thirds of the team's targets in the passing game. It's the highest percentage total in the AFC and second only to the Arizona Cardinals (67.4%).
