Common questions
Why not just always go for it on fourth down? Punting gives the ball away anyway.
Because field position is part of the possession's value. A punt sells this possession for ~40 yards of the next one; a failed fourth down sells it for zero. Sometimes going is right — that's the fourth-down math in Tier 6 — but 'punting = quitting' ignores that the next possession has a price too.
Why does everyone huddle at all? Just line up and play.

Some teams do (see Tempo in the Systems Library). The huddle buys communication: protections, checks, and disguise take words. Tempo trades those words for pace. It's a real tradeoff, not a tradition.
