If I remember correctly, the Legion of Boom era was the last time where a top defense could win game with a mediocre offense.
This then started a short trend to build teams with a defensive focus.. so in 2015 or so, you could have a few teams that were top in defense but at the bottom of scoring offense and still make it to the playoffs.
I believe Bruce Arians' Cardinals at that time had one year like that.
Mike Zimmer's Vikings team around 2015 or so had something like that.
Otherwise, hard to find teams that could win 10 games with a top 5 defense and a bottom half offense.
Closest might be the Bills a few years ago when they had maybe the top defense in the league and was Josh Allen's second year, but 1st full season as QB.
