CrazyEye explains it fairly well for you
I'd just like to expand on 6 and 7:
6: That was actually a TV game so it affects your fans a lot more than regular games. Plus as pointed out, losing is bad, regardless of scoreline.
7. Your drop in attendance is attibuted to 2 things. You lost a few games and you also increased your prices. Also, just looking at the last game, you were playing against the 6th ranked team. Fans don't like to watch losing teams, so even if you're the best team in the league, whenever you're playing against losing teams, expect a drop in attendance.(esp if you do not sell out the arena to begin with)
