3🔍 Why it matters — what to watch for
“The moment their arrow points forward, go in behind,” “break the arrow” — a commentary staple. A person can't suddenly move against the way they're already moving, so taking the reverse of the arrow is the essence of the duel.
Analysts say“Just as the full-back's arrow went forward, the space behind him was used perfectly.”
