I’m a lifelong Astros fan, so until about 9 months ago, that counted here.
Otherwise, I’m a Texas A&M football fan and a Houston Texans fan (used to be an Oilers fan, but they no longer exist).
I root for:
Chicago Cubs (since the 60s). That curse got lifted a couple years back.
Green Bay Packers (since the 60s). That was never a problem (except for the Lynn Dickey years).
Toronto Maple Leafs (since the 60s). I do barely recall the last Stanley Cup they won ('67).
Leicester City FC (since the 90s). That was solved with the dream season a couple years ago.
Foxes and Cubs in the same year; I thought I had died and gone to Heaven. Until I had to mow the grass. 
I’m a Buffalo Bills fan. The last time they won the championship was 1965, the last year the season ended with two separate league championship games. I was in kindergarten.
It should be noted that, while the season didn’t end with them, the AFL had separate champions for another four years after that.
Would be interesting to have seen what the Bills could have done with the Browns that year…
Not as of a little over a month ago! I am a lifelong Washington Capitals fan (basically as long as the franchise has existed, although I was a bit too young to remember the first few seasons), and they finally got that monkey off their back.
I don’t truly support them or follow them (not that I have anything against them; I just don’t follow the sport), but very often at the beginning of a new project my teammates will insist in trying to drag me into a conversation about soccer. When they ask what team do I support, I say Osasuna (my local professional team; currently in Segunda, they’ve never won any cups at either the national or international level; most foreigners have no idea who the fuck those guys are).
There is a moment of silence and they leave me be for the rest of the project.
They still have those games, only now they’re for the conference title. But I don’t consider it a championship unless it’s the highest level of competition that’s played in the sport.
And if there had been a Superbowl championship in 1965, the Bills wouldn’t have been playing the Browns. The Packers beat the Browns in the NFL championship game that year.
Both the Bills and the Packers had a 10-3-1 record in the 1965 regular season, both had been underdogs going in to the championship game, and both won their championships with a final score of 23.
Ooops, as usual, my ability to think in terms of seasons got challenged by the Jan/Dec issue. Yes, the Packers, who would have wiped the Bills just like they did the Chiefs and the Raiders. 
But Ray Lewis is a murderer…
As a Bengals fan, I cannot say that I like the Texans. What in the world happened to Schaub anyway?
As a Bengals fan, you’re welcome for the playoff berth last season, and thank you for Cordy Glenn and Preston. Solid pickups, both of them, and in areas of need.
The New York Nets were the last ABA champions, then were raped when they joined the NBA. In the NBA they have played their home games in Hempstead, Piscataway, East Rutherford, Newark, and Brooklyn without winning a title. The only saving grace is that the Knicks haven’t won one either.
In 2013, he hit a sudden, strange run of throwing pick-sixes (throwing them in four consecutive games). He then got hurt, lost the starting job, and wound up in Oakland, then in Baltimore; he kept throwing interceptions in both places (his first pass as a Raider was picked off).
Hello.
My name is Gedd.
And I’m a Cleveland Browns fan.
It’s not my fault. I was born with it. My family was in Cleveland for several generations. Apparently my grandfather was at the very first Browns game! Many have moved but it’s still there; my uncle heads up a Browns Backers group. My dad watches occasionally.
I was never a huge fan but it pulls on me, dragging me to games . . . my wife and I have even been to one together. Why? A family member asked if we were interested. “Of course we are!” we said. But were we really?
I don’t even watch football now, but I know one day, some days from now, my children will be going to Cleveland to see their first game . . .
I’m a Cleveland fan. Go Tribe. Go Browns. Go Cavs as they head back into the NBA wilderness.
That would have been an interesting game. The Browns lost the 1965 NFL championship game to Green Bay, but the Browns were defending NFL champions going into the game the NFL Title game was a relatively close game.
The reason there were two separate league championship games is that there were two separate leagues. The leagues did not merge until 1970. The first IV Superbowls were games between th league champions. The Bills were the AFL champs in 1965.
Yes, but his point is that the 1966 AFL Champions, while champions of the AFL, will never be remembered has having “won it all” (that year), now will they? No, because they got steamrolled by the Green Bay Packers in the “AFL–NFL World Championship Game”. 
And the World Series is played between two teams in separate leagues. But no team calls themselves the champions because they won the league title if they lose the World Series.
I became a SF Giants fan as a kid . Waited until age 50 to see them win the title. Then they won 2 more in 4 years -2010,2012,2014
Yep. Cubs, Blackhawks, Bulls, Bears…all won in my lifetime, though the Bears best be getting going again soon.
Only remaining one is the Fighting Illini football and basketball teams, my alma mater. The basketball team came close but got hosed my the refs. They might get back someday. The football team is probably a lost cause, though I think I’d settle for a Rose Bowl win as good enough. Two losses in my lifetime and the stupid playoffs may rob them of another chance should they win the Big Ten again.
I’m a Falcons fan. Enough said.
Really, too much has already been said. Ignore the first 4 words of this post.
