Ha! I though I was the only one that posted CFL over here.
For future reference always take the Dog in the Grey Cup (WTN) Whatever The Number (9-1 ATS the last 10 years). The lines for this game seem to always be geared heavy towards the favorite. Too much focus on records and what a team did in their last game. For a championship game it's still lightly wagered, and most of it is Degenerate action at that. So most of the bets will go with the favorite, and thus the oddsmaker has no choice but to juice it up more than any other game.
