Every game starts on the favorite — the betting line where one exists, otherwise the better team by last season's efficiency margin plus home field. Change any pick and the standings, the tiebreakers and the projected playoff bracket all recompute. Your picks are saved in this browser, and the address bar always holds a link that reproduces them.

Where this tool stops. Head-to-head, common opponents, opponents' records and overall records all follow from your picks, so those steps are computed exactly as written. A step that needs a computer rating, a committee ranking, a scoring margin or a coin toss cannot follow from picks — when a tie reaches one, the page says so and shows the order it used instead.

Tiebreaker procedures as published by each conference and summarized by ESPN and CBS Sports for the 2025 season. Conferences do revise them; the steps are printed here so you can check them against the current rulebook.
