Most Playoff Appearances -- NFL Teams, 1920-2017

The Buffalo Bills clinched a Playoff berth today. The last time they did that was in 1999. They were the last major league sports team to have not made the Playoffs in the 21st Century -- although their last Playoff game was the game of January 8, 2000 against the Tennessee Titans known as the Music City Miracle.

Now, the teams with the longest droughts are: MLB, Seattle Mariners, 2001; NFL, Cleveland Browns, 2002 (they completed the NFL's 2nd 0-16 season today); NBA, Minnesota Timberwolves, 2004; NHL, Carolina Hurricanes, 2009.

On this list, ties are broken by more NFL Championships (not just most Super Bowls), then more NFL Championship Game (including Super Bowl), appearances, then more Conference Championship Game appearances, then more Division Championships, then by fewer seasons of play. This also includes NFL Championships won in the pre-Playoff era, 1920-31:

Of course, some context is needed. Of course, "most times made Playoffs" is weighted toward the older teams. So how about percentage?

The 1st column to the right of the team's name is the number of times they've made the Playoffs. The next is their number of seasons. The last is, on the average, every how many years they make the Playoffs.
