The Seahawks won SB XLVIII in 2014. (2013 season)
The SuperSonics won the NBA championship in 1979. And now they no longer exist.
The Mariners are… still waiting.
Let’s see I grew up in Cleveland so …
OK there’ve been a couple of moments. The Browns were very good in my young pre-SUper Bowl life winning NFL championships in 1950 1954 1955 1964. The last is the only one I really remember.
We won’t talk about the Indians/Guardians who last won it all the year before I was born. I don’t follow the NBA at all but thank Dog, LeBron James gave Cleveland another Championship in 2016 - long drought since 1964.
In hockey I follow the Bruins as Cleveland didn’t have an NHL team while I was there and I started to follow hockey while at college in Cambridge. (MA not England), The Bruins won it all in 1970, 1971 and 2011.
Nearest I’ve come is the England rugby team of 2003. We won the world cup and the six nations grand slam that year.
This year, I decided that I just wasn’t feeling any sports except for ultramarathons, so I haven’t watched any football or baseball games all year.
So, of course, the Braves win their second World Series in Atlanta - I was an avid fan back in '95, when they won their first.
Likewise, Georgia ran the table in the SEC for the first time since 1982, and is favored to win the College Football Championship. (I wasn’t a Dawg fan when they won it all in 1982, so that doesn’t really count.) Frankly, I’m a little nervous about watching them now.
The Browns won a couple of NFL championships before I was born, and lost some heart-breaking playoff games under Brian Sipe and the Kardiac Kids, back when I was a lad. Then, of course, Art Modell ripped the heart out of Cleveland, a wound that was only slightly assuaged when the NFL gave us our team back. Who then proceeded to reel off a string of losing seasons, revolving quarterbacks and coaches, and lousy football, culminating in becoming only the second team in NFL history to lose every game in one season. Fortunately, things are looking up, thanks to Baker Mayfield and Nick Chubb. But to be a lifelong Browns fan is to have your hopes ground in your face again and again.
As far as the other Atlanta teams, I’ve never been a Falcons fan, so don’t care about the two Super Bowls they’ve lost. The Uniteds won a championship recently, but soccer bores me, so I’m indifferent to them, as well as to the Hawks (and the Thrashers and Flames, when they were here).
I’ve been a New Orleans Saints fan since the mid 80s, when my dad bought season tickets – their Super Bowl win in 2010 is my fondest sports memory of all time. My brother, me, and my dad all watched together by connecting on zoom from 3 different cities, and it was a blast.
I’ve been an LSU Tigers fan since attending school there in the late 90s, and they’ve since won 3 national championships (but it was after I graduated). Those were also lots of fun, especially the 2019 season in which they were so dominant through the entire season.
First of all, @ekedolphin, we share a lot of the same teams. The only one we differ on is baseball, where my Cubbies won it all in 2016, breaking a century-plus drought.
Nemo’s?
mmm
Don’t beg - it’s undignified. 
I would have loved to have seen that Tourney. One more reason (among many) to hate COVID. I really wish they would have gone with the “16-in-a-bubble” that was floated.
Packers won in 1997 and 2011. Braves won in 1995 and LAST MONTH! Bulls - well, duh. Red Wings - '97, '98, '02, and '08. The Minnesota Lynx - 2013, 2015, and 2017. The Iowa State Cyclones…not really much in my fandom. Apparently some dance team, and a couple wins in wrestling and cross country. How they never took a title with Cael Sanderson is still beyond me. The Colorado Springs Switchbacks have yet to win, but they’re poised to compete for it this year.
Cal won the national basketball title in 1959.
A bit before my fandom, such as it was, which didn’t begin until I started there as a student (even then, shortly after the Free Speech movement and shortly before the height of the antiwar protests, the intensity of sports teams fandom was muted, to say the least).
Though, this was right around the time that I decided, since all the other kids cheered for the Giants, I was going to be a fan of their nemesis, the Dodgers. Though my fandom did not extend to actually following the team. Mostly it meant that when we were playing pickup games, I was Sandy Koufax or Don Drysdale.
I was in HS in Portland in the mid-'70s. After the brutal disappointment of the whole Pre debacle, watching the Trailblazers win in their first appearance in the finals was uplifting. I am not a basketball fan in the least, but blazermania so saturated the city at the time that I actually sat down and watched them take it all against Dr. J’s sixers in game six. Then we went out for dinner, because my dad turned 50 that day.
I’m across the pond, so we’re talking Soccer and Rugby Union…
My Dad took me to watch Tottenham Hotspur (Spurs) a few times in 1960, when they did the ‘Double’ - winning the top League and Cup.
In 1966, my Dad and I watched England win the Soccer World Cup.
In 2003, I watched England win the Rugby Union World Cup.
Not technically a bar, The Maltese-American Club. Somebody knew someone who was a member.
This! I’m around 20 years ahead of Andy, but those NCs were certainly sweet. Plus that Saint Super Bowl win in 2010 was awesome.
Soccer here, 2009, F.C. Barcelona won it all: the Spanish League, the Spanish Cup, the Spanish Supercup, the UEFA Champions League, the UEFA European Supercup and the FIFA Club World Cup. We called it the sextete, I still have the T-shirt. It was the first team to ever manage. Bayern Munich did the same 2020. After thrashing Barça 8 - 2 in the quarter finals… (grrrr! Still hurts).
I’m from Pittsburgh – they don’t call us the City of Champions for nothing.
Steelers – 6 Super Bowls. 1974, 1975, 1978, 1979, 2005 and 2008. We were the first to win 6, BTW. (Among other firsts)
Pirates – 5 World Series. 1909, 1925, 1960, 1971 and 1979. Sadly, due to poor ownership, we really suck. (I’m not a baseball fan, but I do think of myself as a Pirates fan, if that makes sense)
Penguins – 5 Stanley Cups. 1991, 1992, 2009, 2016 and 2017. I’m a little leary of the upcoming sale, but Mario Lemieux is still going to be involved, and they say it’s actually going to be for the best. fingers crossed
If you look, our teams tend to win championships together. 
(BLACK AND GOLD, BABY!!!)
My only really significant fan investments are in the Blue Jays and Raptors, so I’ve seen both; the Jays in 1992 and 1993, and the Raps in 2019. So I can die having seen that. Some fans never get that.
I was a teenager in the 1980s and my two baseball teams were the Mets and Red Sox. In 1986 they played each other in an epic, legendary, unbelievable World Series. The final inning of game 6 is the closest I’ve ever been to thinking I had witnessed divine intervention.
The Mets (who had my ultimate loyalty despite my fondness for Boston) finally won in 7, and I went to school the next day wearing a Red Sox hat in tribute to their effort.
Even then I knew it would never get better than that and I pretty much stopped watching baseball. Only during the pandemic, with a lot of free time, did I come back to it.
Yankees, Giants and Devils. So yes I’ve had a few in my lifetime but they are all in a drought right now. Any feelings I had towards the NBA I lost a while ago. Couldn’t even tell you who won last year.
