Saskatchewan has one of the best defenses in the CFL. The Roughriders have held their first two opponents, Edmonton and Hamilton, to a combined 29 points.
Montreal is down its starting QB, Vernon Adams. He's in COVID-19 protocol. There's not much of a dropoff from Adams to backup Trevor Harris. Adams is more dynamic, Harris less turnover prone. The Alouettes are without their top running back, injured William Stanback.
Roughriders QB Cody Fajardo wasn't too sharp last week despite playing a horrible Edmonton defense. Saskatchewan is averaging only 17.2 points in its last seven road games going back to last season.
Montreal lost some key defensive players from last season. But the Alouettes held the Tiger-Cats to 20 points last week. They catch a break in that the Roughriders have far less practice time having just played last Saturday also on the road at Edmonton.
