If an opposing team can study previous games and determine what you are likely to run in certain situations, they can be better prepared to stop you. "If you are making random choices, it's harder to respond," Ayres explains. "A-11 offers a kind of controlled randomness."
The closer a team gets to total randomness, says Ayres, the harder they are to beat. "Any coach would be much better off using a cheap [Microsoft] Excel random number generator to make their decisions."
