Fans always think of the narrow losses and believe they were "that close" to being much higher up the ladder. But that's not really accurate for the Tigers. Our for and against is by far the worst of the top 12 teams and while it's easy to remember the tough losses we've also jagged some scratchy wins: we absolutely burgled the Sharks at Leichhardt, scraped a win against the Roosters even though they scored more tries and had about 12 players out, and needed a field goal to get over the Titans.
You say we've been in every game except the Storm one, which is more or less fair (though I'd also include the 36-2 flogging by Penrith) but equally we haven't put many teams away. We're nine wins and 11 losses excluding Melbourne - more or less 50/50, which is pretty much what you'd expect.
On balance, 9th-13th is about right.
