I already answered this in the other thread you made...No need to make another thread. Anyway, it doesn't matter if you have won your last 20 games before last week. You lost the last game, and not only that, you lost it to the number 1 in the other conference. So your fans would have been hoping to see a great match, instead you were easily beaten, hence the fans were disappointed and of course some didn't go to your next game.
Either that or it was raining on the day :P
