Lol.
I think a lot of football fans aren't caught up to the reality of what NFL defenses are actually doing.
It should be common knowledge that they play base around 1/4 to 1/3 of the snaps in most games on average.
It varies based on the opponent.
They generally but not always play Nickel against 3 WR sets.
Damien Wilson has been the SLB the past 3 seasons.
His snap counts:
2018 27.9%
2017 31%
2016 26.9%
Wilson did play some snaps in 2 LB sets in 2017 but it was minimal.
In 2018 slot CB Brown played 67.3% of the snaps.
Since the SLB exits when the slot CB enters the game, the 11th spot on defense can be considered shared between them.
CB Brown 67.3% + SLB Wilson 27.9% accounted for 95.2% of snaps at that 11th spot.
The other 5.8% comes from any snaps missed by Brown/Wilson or groups without either of them such as Big-Nickel with a Safety instead of SLB or Slot CB.
Oddly the Patriots used 3 WRs (11 personnel) less than most other teams in 2018.
The Rams used 11 personnel more than any other team.
