First season actually watching,came from a family that only watched the superbowl, my only local options are the jets which I feel are just a pathetic franchise and theres nothing about the giants I enjoy, but I've genuinely been hooked on buffalo since the beginning of the season,I actually like the players which I can't say about the jets/giants, so i reiterate my initial my question.
For a sports team, bandwagon fan is probably the most common term in the US. Bandwagoner would be the more general, non-sports case, and most everyone would know what you mean although it's not very a common term.
If we're focused on sports, fair-weather fan also works well. It does have a slightly different connotation than bandwagon fan, in my opinion. A bandwagon fan is more likely to follow any team that is currently popular. A fair-weather fan is more likely to follow only one team (in a particular sport), but is likely to only act like a fan when that team is doing well.
e.g.:
"Dan is a bandwagon fan. He used to be a Yankees fan, but now he says he's a Red Sox fan."
"I never saw Dan wear a Red Sox jersey even when he lived in Boston, but now that they've won a World Series he wears them all the time. He's such a fair-weather fan."
It would be called a faddist.
A fad is any form of behavior that develops among a large population and is collectively followed enthusiastically for a period of time, generally as a result of the behavior being perceived as popular by one's peers or being deemed "cool" by social media.
Though the term trend may be used interchangeably with fad, a fad is generally considered a quick and short behavior whereas a trend is considered to be a behavior that evolves into a relatively permanent change
