who has the most shutouts in the modernish era?

[uh-oh]

with the ravens getting their 3rd shutout of the season today, i decided to google, and can't really find shit.

so i googled the 2000 ravens, which had 4 shutouts, all in the regular season, and the 85 bears, which had 4 shutouts, 2 of which in the playoffs

while reading the ravens stat it said the last team to do it was a 70's steelers team, but im guessing they meant the regular season since the bears obviously did it.

but word who has shut people out though the most
