Question 1

What is the 17-0 NFL Challenge?

Accepted Answer

The 17-0 NFL Challenge is a free browser game where you draft an all-time NFL roster from any era and simulate a full 17-game season attempting to go undefeated — something no real NFL team has ever done in the modern 17-game format.

Question 2

Has any NFL team ever gone undefeated?

Accepted Answer

Only the 1972 Miami Dolphins finished a season fully undefeated, including the playoffs, going 17-0 across a 14-game regular season plus postseason. No team has gone undefeated in the modern 17-game regular season.

Question 3

How do I build a team that can go 17-0?

Accepted Answer

Draft the highest-yardage, highest-touchdown seasons from any era — legends like Peyton Manning, Jerry Rice, Barry Sanders, and Tom Brady. Balance your roster across positions and eras for the best shot at a perfect season.

Question 4

Is the 17-0 NFL Challenge free to play?

Accepted Answer

Yes. The 17-0 Challenge on Franchise Lab is completely free to play in your web browser. No download or account required.
