I formation

The aye: McKay learned the “I” formation from a young junior college coach: Don Coryell.

This 49ers offensive machine could churn out 100-plus rushing yards with the two of us lining up in the “I” formation.

Nebraska last week showed some of the offense Frost played in when he was the quarterback in the mid-1990s, having Dedrick Mills line up at fullback in the I formation.

After Sunday’s game he went as far as to say he would only play Peterson if the Redskins have a game “where we run the ball 55 times a game in the I formation.”

Long discarded the I formation he had long favored before this season and moved to the spread, hoping to capitalize on the system that quarterback Ryan Agnew ran in high school.
