Every year during the postseason, for any sport, there are always a select group of fans that decide it's unacceptable for previously uninterested people to root for "their team". They go on to call them Bandwagoners, and explain to you at nauseum how they have "followed the team since (insert obscure athlete name with equally obscure achievement)."
I'm a Giants fan, and have been since the Candlestick days of my youth in the 80's. Will Clark, Candy Maldonado, Rick Ruschel, and the rest of the guys who guided my own baseball career were fun to watch and root for. It was also fun rooting for guys like Dennis Eckersly, Nolan Ryan, or any other ball player who I found exciting and played the game the way it should be played.
I love baseball because of it's complexity, simplicity, and everything in between. If you enjoy the sport, then you shouldn't care who decides to follow the team. It's always easy to spot the Fan who likes the game because of blind pride in their team, rather than the abilities of the players who play it.
Too prideful to admit enjoyment of another teams success when your team is out of contention? I think it's time for another hobby my friend.
