Harvard and The Flying Wedge and Horse's Neck

Lorin Deland, a Bostonian and student of military tactics, borrowed from military tacticians of the late 1800s by creating football plays using miniature figures set up on a tabletop football field. One output of his tabletop generalship was the Flying Wedge, which remains among the game’s most famous designed plays. Harvard sprung the Flying Wedge on Yale when they kicked off to start the second half of their game in 1892. — www.footballarchaeology.com
