So if you take Scotland getting the 12.5 points start you not only win if they pull off a miracle against their old masters, but you have plenty of room to move in a game that should see the scoreboard tick over in multiples of three.
After all, a 12.5 point start means England have to kick four more penalties or drop goals than Scotland to cover the point spread.
In other matches punters should be wary of the big-name teams giving away too much of a start to the minnows, even though many of the lower-ranked teams are exhausted.
Australia and Wales will be confident about beating Russia and Fiji and could make changes in their games to protect elite players for the quarter-finals.
That could even apply to South Africa should they get a points buffer on Samoa, although the latter's defensive qualities make their 17.5 point start seem generous.
Money makers
Scotland with a 12.5 start against England. Have you ever seen Six Nations? Enough said.
All Blacks to cover the points spread against Canada as long as Carter plays. The ABs have too many points of attack.
Radike Samo to score if he plays on the wing for Australia against Russia. Julia Gillard could score on the wing for Australia against Russia.
