"No one believed in us!!!" would actually apply. Players love to say that after victories, but most of the time it is just something they say to themselves to get fired up and they were favored in most of their games. It isn't common for a team to be SO underrated at the start of the season and to have NEARLY EVERY game be the "trap game" that is supposed to end the magical run.
If they pull it off, and I now believe they can (I would never have bet on that before the season), then they can call out everyone--even many of us cougar fans.
...and let them keep those chips firmly planted on both shoulders going into the playoffs, because you know they'll be underestimated there as well.
