The Bulldogs will need to cause the biggest upset this century to beat Penrith on Saturday, with TAB placing them as $21 outsiders against the Panthers, who are $1.01 to maintain their unbeaten run.

TAB’s record for the longest Head-to-Head odds still remains with the Wests Magpies, who were priced at $31 in 1999 against eventual premiers Melbourne, with a line of +42.5. They lost 44-14. If Canterbury’s odds remain at $21 it will be the equal second longest price a team has started.

Penrith remain title favourites at $2.75 after thumping South Sydney, who have moved from $5.50 out to $7.00. While after being as long as $81 in Round six, Manly are into $15 with their win over Parramatta.

The Sea Eagles are closing the gap on the drifting Roosters, who are now out from $10 to $13 after their shock loss to the Broncos. Manly are considered a genuine top four hope following a move from $6.50 to $4.00 in that market.
