20-0 is an innovative, free browser-based roster-building game that invites football fans to explore a compelling question: can you assemble an all-time great team to achieve a perfect season? In this engaging independence project by Gamerank, players randomly draw from historical teams and eras, selecting legendary players to fill each position and creating a unique roster. Every player's performance is evaluated using an era-normalized rating system that account for the context of their playing time, allowing fair comparisons across decades. The gameplay includes a simulated season that projects win probabilities based on roster balance, encouraging strategic drafting.

Players can also participate in a Daily Challenge for a chance to rank against others, or engage in head-to-head matches. With ongoing updates based on player data, 20-0 remains a dynamic experience that connects fans through the thrill of competition and nostalgia for football's greatest athletes. Join the fun, draft your team, and see if you can achieve that elusive flawless record!
