Gloryhunting is gloryhunting.
You just watch how many of your UTD mates are still buying kits in a decade if their decline keeps up.
They're more likely to stick with the American sports teams they "support" because the cap and draft system means that every team stands a good chance of rebuilding. It's far easier to be loyal to your team in those circumstances.
When it comes to Footy you get the likes of
@Yank who say they're going to support the RS or Bayern instead.
Those types never really had a connection with the team beyond liking a specific player, because they're successful, or they like his instagram videos or their skill moves on FIFA.
I'm not suggesting it's all of them but it definitely seems more prominent over here to have people support a team they have no tangible connection to. Back in Liverpool you'd get the odd manc gloryhunter (expect the wools) but the abuse/disdain from the locals for these types keeps it at bay for the most part(Southern Kopites excepted).
