That's a betting line. It's offered to punters with the risk attached, and the TAB has a way of judging the betting lines on a game. It's your choice if you take the risk. I have the Tigers winning. The margin means nothing in tipping the win. Personally I think they will thrash the Saints, but I wouldn't bet on the margin.
I don't understand the question Angelo, you make a statement and stick a question mark on the end of it, it's not a question mate. So it's hard to give you an answer only to say, I'm not a fortune teller so I can't say if they'll win by 18 or not, why 18? You are right though, the Tigers might not win, there is every possibility that could happen, so they're my thoughts, I hope we win but we could lose, who really knows mate. It's all guess work.
