I tipped that to be the game byso.
In my reasoning I think the tigers will win a close encounter with the Dragons.
They struggled to beat the Sharks. Plus, I think the fact they will have played just 2 games in the last month will get too them. The tigers are an 80 minute team. They can go with the Dragons and I think they have the ball skills to break the line and the defense to stop Gas and their forward pack.
As for the eels and cowboys. If the cowboys can win, they can take the comp. However I think it wont even be a contenst.
Tigers v Eels for mine with the tigers taking a surprisingly easy win in the GF.
