Apples to oranges.
Bombers are in the West. Montreal is in the East with two historically bad teams in Toronto and Ottawa. Toronto has one of the worst defenses in modern CFL history and Ottawa has one of the worst offenses, worse than the 2013 Bombers. Even the worst two teams in the West who are not very good in Edmonton and BC are nowhere near as bad as those two.
The Alouettes would have to be exceptionally awful to not finish 2nd in the East over 18 games. It's not that great of an accomplishment. Winning in Calgary is an accomplishment, but that historically bad Ottawa team also won there this season.
