Best/Worst decades of football

So, I wanted to see who had the worst/best 10 year stretches in football since the merger. I'm only concerned with regular season win%, for the entire decade.

These are the worst. This is sustained sucking. The names won't surprise you. And to be fair, this was the Saints first 10 years in the league. The "new" Browns, and Bucs, were a decade in before they went on their worst 10 year run.

Bengals(1991-2000) - .29 win%
Lions(2000-2009) - .26 win%
Saints(1967-1976) - .24 win%
Bucs(1985-1992) - .23 win%
Browns(2008-2017) - .23 win%

Here's some of the best decades of all time. Don't know if I got them all. Probably missed a couple. Yes, the Pats are ridiculous . I probably could have made more combinations but I was done. The 49'ers also fared well. I find it funny that last on this exstensive list is the great Cowboys 90's dynasty. The 70's Steelers show up as the 23rd best decade. Thank god it isn't just about regular season win%.

Patriots(2003-2012)(2007-2016)(2010-2019) - .78 win%
Patriots(2006-2015)(2004-2013) - .77 win%
Raiders(1967-1976) .77 win%
Patriots(2009-2018)(2005-2014)(2008-2017) - .76 win%
49'ers(1989-1998) - .76 win%
49'ers(1983-1992)(1984-1993)(1987-1996)(1988-1997) - .75 win%
Cowgirls(1968-1977) - .75 win %
Vikings(1969-1978) - .75 win%
Vikings(1968-1977) - .74 win%
49'ers(1985-1994)(1986-1995) - .74 win%
Patriots(2011-2020) - .73 win%
49'ers(1985-1994) - .73 win%
Dolphins(1970-1979) - .72 win%
Steelers(1972-1981) - .71 win %
Patriots(2012-2021) - .71 win%
49'ers(1990-1999) - .70 win%
Packers(1995-2004) - .68 win%
Steelers(2001-2010) - .66 win%
Raiders(1976-1985) .66 win%
Packers(2007-2016) - .66 win%
Broncos(1996-2005) - .66 win%
Steelers(2002-2011) - .65 win%
49'ers(1991-2000) - .65 win%
Packers(2012-2021) - .64 win%
Bills(1990-1999) - .64 win%
Cowgirls(1990-1999) - .63 win %

 

In the end it's all about Super Bowls. Vikings and Bills part of nice decades but zero Super Bowls. Saints and Bucs, total 3 Super Bowls.

How strange would it be for the Lions and Browns to finally reach the Super Bowl and play each other.

 

Yeah....I wouldn't watch that until the summer time when they show the replay.
