Oh yeah, I know people that are like Mavs/Spurs/Rockets fans and it makes me sick. It's not just the "you triple your chances" thing, but it's so much more the fact that you never get the true high. The true "holy **** 'we' did it" high.
I went to a large number of Marlins games growing up. I'm talking about 1999 when they almost lost 100 games and the OF was like Todd Dunwoody and Mark Kotsay. The team was absolutely atrocious. The stadium was empty. But it was baseball and baseball is my #1, plus seats were dirt cheap since nobody came. 2003 is the highest sports could possibly be for me. It was a team that was varying degrees of mediocre to terrible for 5 years and came out of nowhere to win it all. I remember that year going on summer vacation to a Marlins game in Chicago (which was pretty cool, Sosa put the game winner out of the stadium off of Pavano) and being ridiculed by Cubs fans about how they finally found the 4 Marlins fans in the world (super nice time/people though, def recommend going to a game at Wrigley if you haven't). I remember sitting in restaurants with my dad in the middle of July going "you know, this team is pretty good. Pavano is pitching great and Beckett is awesome". I remember being in the upper deck when Pudge held on to the ball when Snow collided with him in g4 of the NLDS and going nuts. I remember watching ESPN after Beckett won g5 of the NLCS and rolling my eyes at all of their segments about how "sure teams have come back from down 3-2 BUT THAT WASN'T AGAINST PRIOR AND WOOD". I remember thinking that while Steve Bartman was awesome, the true heroes were Moises Alou for losing his **** over it and the bad Alex Gonzalez for booting a routine double play ball. And I remember Beckett tagging out Posada and a full blown party breaking out on our street.
That's it. That's why you watch sports - for that kind of run. You know how we watch all that bull**** in WWE for those few moments of something elite? That's what sports fandom is too I think. And you lose that incredible high when you remove yourself from all the lows by switching to the good teams while yours is bad. I'll never understand it. They rob themselves of the best part of sports.
Can only shake my head.
