That number seems high. I can't think of 12 chances.
Nationals: 2012, 2014, 2016
Capitals: 2017, 2016, 2015, 2012, 2011, 2009
Wizards: 2017, 2015, 2014, 2005
Redskins: 2005, 1999
So really, more than 12
The last team to actually make it? The one everyone thinks of as the biggest chokers: the Washington Capitals in 1998. Peter Bondra had more heart and guts than most of these dorks, combined.
