Orin's defection: a football field is a tennis court tugged long
Consider that a football field is basically just a grass tennis court tugged unnaturally long, and that white lines at complex right angles still define tactics and movement, the very possibility of play.
Context
The lines that bound and define play, ported wholesale: a football field is "basically just a grass tennis court tugged unnaturally long," where "white lines at complex right angles still define tactics and movement, the very possibility of play." It's the enabling-form insight the whole institution is built on — that the game exists only inside its geometry, that the lines don't constrain play so much as make it possible. Orin didn't switch games so much as change the dimensions of the same bounded rectangle; the court's grammar of limits is what let his one shot find a second life.
