The 17-0 Challenge is a free, browser-based NFL team builder game. Spin the slot machine, draft a 9-man roster of football legends from random teams and eras, and find out if your lineup can go a perfect 17-0 — the undefeated regular season only the 1972 Miami Dolphins ever pulled off (the 2007 Patriots came one game short at 18-1).
