I’m tying together data from a series of older forum posts, breaking down video of the eighth game of the 1985 season, a game between the Chicago Bears and the Minnesota Vikings.

The first play of the game is a 46.

There is a five man front instead of a 6 man front because of the one man backfield and the slot receiver. The adjuster has to come out of the line and cover the slot man. The linebackers shift to the right side of the offense and the weakside linebacker is aligned with the tailback and the strongside linebacker is just outside the tight end. 99, Dan Hampton, is face up with the center. The two linemen beside him are on the guards. The offensive tackles are uncovered.

This next one isn’t as clear, the linebackers (such as they are) are moving into position as of this point, but look at the line spacing.. three linemen on G,C,G and the free end outside, 95 Richard Dent. This play occurs with 6:29 left in the half of the 1985 Chicago-Minnesota game.

This next image a bit after the above, on a play where 22, Duerson, intercepts Tommy Kramer. This is about as classic a 46 front as I’ve seen so far. It’s easy to count 6 shadows along the line, see the two players at linebacker depth (Duerson on top). I’d ask if this really could be confused with a 3-4 of any kind. As a “4-3” it’s awfully bizarre.

Ok, this screen I originally tagged as possible 46 but the more I look at it.. it’s a 46. This is from a 2nd and 10 play at the very end of the first quarter. The Vikings are threatening to score.

This 46 came just before the 2 minute warning of the first half. Ironically the Bears are playing 46 when the Vikings need to pass to get downfield. The score is 10-7 and the game is close.

This 46 came at 1:15 left in the second half on a 3rd and 5. It ended up well for the Bears, but only because Tommy Kramer overthrew a wide open receiver downfield.
