What is it?

The double wing offense features five offensive linemen, two tight ends, two wingbacks, a fullback and a quarterback. The linemen are stationed no more than six inches apart. The wingbacks line up at the same distance from the tight ends, and the fullback shadows the quarterback.

Most double wing offenses run variations of five basic running plays: Power, sweep, trap, counter and wedge.

Why run it?

Double wing is popular nationwide among coaches with limited depth and small offensive linemen, because it allows them to be successful with deception and double-teaming, churning out long drives that ultimately shorten a game.

Defenses typically have trouble picking up which back has the ball. There is also the temptation to “bite” on the run, leaving yourself open for a quick slant pass and a big gain at your expense.

Any reason to shy away from it?

It’s not a great catch-up offense in the second half of a game. Some fans and little-used receivers might lose interest.

Who invented it?

Don Markham, a California high school coach, devised the double wing in the 1970s and has won state championships at three different schools.

How successful is it in Maine?

Gorham has won Class A and B regional titles. Boothbay captured back-to-back Class C championships in 2001 and 2002. Skowhegan is one of this year’s favorites in Eastern Class A.
