THE STAMPEDERS WILL WIN IF ...
They score early to take the crowd out of it and make a big stop on defence during the Alouettes first possession.
If they accomplish that, the visitors could grab the momentum and hold it for a long stretch with their clock-killing offence.
All weapons on offence must be clicking for the visiting team to be victorious, but the defence is looking more and more like the key.
Cornerback Brandon Browner has been hobbled all week by an ankle sprain, while star defensive end Mike Labinjo is suffering from the flu.
Those two will be sorely missed if they don't play, and it could hurt just as much if they are ineffective due to their ailments.
THE ALOUETTES WILL WIN IF ...
They can manage the pressure of being at home and not make mistakes on offence to give the visitors life.
In the last meeting against the Stamps, Als quarterback Anthony Calvillo threw three interceptions and that proved to be the difference.
The rest of his team didn't really help out, as the defence had probably its worst outing of the season.
This is a meeting of the two best offensive teams this season, so that should mean whichever defence plays better could make the difference.
The Alouettes are led by middle linebacker Reggie Hunt and defensive end Anwar Stewart, both of whom are veterans who have been in these situations before.
Montreal has a wealth of Grey Cup experience being this is its sixth trip to the big game since 2000, but the Als have only one win to their credit.
