First off, weather factors here. It's going to be cold with a 70 percent chance of snow.

Both teams are in good defensive form, too. 

Hamilton is the No. 2 defensive team in the CFL giving up 17.4 points a game. The Tiger-Cats opened the playoffs with a 23-12 win against Montreal last week. Hamilton held Montreal's stud running back William Stanback to 46 yards on 16 carries. 

Toronto has held its last three opponents to an average of 15 points. Defensive guru Chris Jones was added to the Argos this season as a consultant. He could make a difference here with a strong defensive game plan.
