Ok I'll be the first to admit, I'm not a true fan at all but even I've noticed that these guys used to play pretty good and now they're awful!!! Can anyone please explain to me why???

It's not that it really bothers me personally, but a few close friends of mine are fans, real fans, as in use the terminology 'we won' or 'we lost' despite the obvious fact that they didn't play (am I the only one who sees a flaw with this phrase?!). Point being that I can't go and ask these guys why 'their' team is rubbish without serious risk to my well being, so anyone here got any answers??
