Vikings 3-4 Base Defense vs 12 Personnel. Part 1 3-4 With Split Field Coverage Concepts

The Vikings were a top defense right now only allowing 10 points per game. They are the the 2nd best rushing defense in the NFL, allowing just 71 yards per game.

This article looks at the Vikings defense against 12 personnel. They have been very effective in their run defense, and they primarily do it with 2 fronts vs 12 personnel. Brian Flores likes to use both the under front and his 3-4 front when playing vs this personnel grouping on early downs. He will mix in some pressures with both looks.

The defense has helped them start 3-0 and it starts with their run game. Again they are only allowing 71 yards per game and 3.6 yards per carry. That is very impressive.

In this article let’s look at the 3-4 front

Here is the Mike pressure from the 3-4 front.

They play the concept with quarters.

Another look at the same pressure with a 2nd wr away from the blitz. In this situation, the OLB on the weak side will match #2 to the flat. This is the adjustment vs a #2 wr weak.
