NFL playoffs get underway with wild card round games being played Saturday, Sunday and Monday. The Kansas City Chiefs earned the No. 1 seed in the AFC and the Detroit Lions earned the No. 1 seed in the NFC for the first time in franchise history.

The NFL playoff bracket is ever-changing and differs from the static formats common in other leagues. That means that seedings play a big role in future matchups. The No. 1 seeded Chiefs and Lions will face off against the worst team, based on seeding, remaining in their conference in the divisional-round.
