The current best overall NFL record depends on the criterion you use (career all-time wins, all-time winning percentage, or the best single-season record). Here are the common benchmarks:

• Best all-time regular-season win total (career): Historically, the Green Bay Packers hold the most regular-season wins in NFL history, with over 800 wins through recent seasons. This reflects long-term success across many eras.

• Best all-time regular-season winning percentage (career): The Baltimore Ravens have among the highest regular-season win percentages in NFL history, reflecting sustained success since their inception.

• Best single-season record (undefeated or 16-0 seasons): The New England Patriots (2007) and the Miami Dolphins (1972) are notable for finishing the season 16-0, tied for the best single-season records.

If you’d like, specify which measure you want (career wins, career win percentage, or best single-season record), and I can give you the exact current leaders and their figures.
