Are the Rams the first team to win back to back games without allowing their opponents to score any points? If not, what other teams accomplished this feat; and what is the longest streak of holding your opponents to no points in the NFL?
According to this Wikipedia list of NFL records by team, the "Most Consecutive Shutout Games Won or Tied" was 13 by the Akron Pros over the 1920 and 1921 seasons. They finished the 1920 season with 5 straight shutouts (the last 2 were ties), and they started the 1921 season with 8 straight shutouts (the last one was a tie).
But the most consecutive shutouts in the modern era is three. This was accomplished by the 1970 St.Louis Cardinals (3 straight shutout wins) and the 1976-77 Steelers (they had 3 straight shutout wins in the middle of the season, and also had 2 straight shutout wins at the end of the regular season and a shutout win in week 1 of the 1977 season). A philly.com article mentions this:
The only NFL teams (since 1940) to have three consecutive shutouts were the 1970 Cardinals and the Steelers, who did it during Games 7-8-9 of the 1976 season and closed out that season with a pair (Games 13-14) and started 1977 with one (Game 1).
