montreal is currently 8-4, and are basically a lock to win the division, they wold have to go 0-4, and winnipeg or Toronto would have to go 4-0 in order for them to lose division title in regular season. Even then, it would be a tiebreaker, not sure on the tiebreaker rules. Montreal plays Hamilton (2-12) twice out of their 4 remaining games, and are a 6.5 point favorite this weekend against sasktchewan.
Montreal will get a BYE in the first round of the playoffs and will jump right to the division final game, they will likely be quite a heavy favorite in this game. Anyone who took a shot on Montreal at +350 will be able to take a shot on the Point Spread Dog in this game and hope for a middle. Ideally montreal would win the game, but not cover, so you could pick up some nice cash on the way to the final game if everything goes perfectly.
Assuming montreal can win the division Final, which should be easy as they will be a heavy favorite, you now have Montreal +350 in the grey cup.
Now the Grey Cup this year just happens to be in Montreal, so it will be a home game.... 60 000 rabid fans at the Big O will cheer on the team.
Regardless of wether they win or lose the big game, they will surely be the favorite in the big game. They will be at least a 2 or 3 point Favorite, if not more against BC or Calgary the best teams in the west. So you can hedge the final, either go with the western team + the ponts or the Western team on the ML.
*** Of course any major injury to Calvillo or other key montreal personel, and all is over, but heck, that is why they call i gambling***
