I would have thought that the likelihood of different opponents would factor into the Tigers odds.Right, again some simple mathematics.
Richmond are paying $4 for the flag.
If they are $1.3 to beat St. Kilda on the weekend, and start $1.9 equal faves with Port the following week, that would mean they start $1.60 against (likely) Brisbane in the Grand Final.
The chances of a Geelong or Collingwood opponent would have Richmond at shorter odds than it would be if you knew it was Brisbane.
