"He's a well-developed quarterback," Raymond said of Butler. Tubby believes that Butler can pass more effectively from the Wing-T than from a pro set because his complex offense provides better deception.

"Three different players can carry the ball, so the defense can't always pass rush," Raymond says. "Butler has a better chance because the skill requirements are shared."

The Tubster is also quick to point out that the Wing-T is, in many ways, a highly-developed passing offense. "The Wing-T implies Neanderthal," he said, "but it doesn't have to."

Rogerson agrees. "Eight different receivers caught the ball last week," he said. "Our offense takes the pressure off him [Butler]."

Princeton modifies its Wing-T into a number of different formations, and many football analysts believe that in practice, Princeton's Wing-T is far less conservative than Joe Restic's famed Multiflex.

Both teams today will use a basic formation consisting of a wingback, two set backs, and a split end. But Princeton, despite the onus of the supposedly ground-hugging Wing-T formation, will almost certainly pass more than Harvard.

This from a team that was one of the last in the nation to run from the Single-Wing offense. Princeton ran the Single Wing--an anthropological relic from the Stone Age--when Dick Kazmaier won the Heisman Trophy in 1951.

Thirty-five years later, the Tigers will line up in the Single-Wing's bastard son, the Wing-T. Only this time they'll have a different standout, a guy with a golden arm.

And a guy in Delaware named Tubby.
