I don't think one's reaction to the result of a game necessarily has to do with being a fan or not. I think it relies more on if you like a team or not, and why. If you like a team because their name sounds cool or they recently won a Cup, you're probably at best a bandwagon fan until you educate yourself a little more and get invested to the point where you don't ditch them as soon as they start losing. On the other hand, if you truly care about how well they're doing and stick with them even when they're not adequately performing, then I would say you're a true fan. Reactions to games are just that, reactions, and nothing more. Different kinds of fans react differently. There's the overly pessimistic, the realist, the optimistic, the "homers", the ride the high's and berate the lows, etc. It takes all kinds to have a fanbase, otherwise we'd all have the exact same opinions and feelings and it would become very boring very quickly.
For some reason, I see Schneider tearing it up in the regular season and eventually getting the nod for the 3rd spot, with Quick and Howard as 1 and 2, respectively. Miller was great in 2010, but just isn't happy in Buffalo and his play shows it IMO.
