Saskatchewan Roughriders vs. Calgary Stampeders: A Data-Driven Showdown
By The Sportswriter Who Still Thinks the CFL Should Adopt the NFL’s Overtime Rules
Key Statistics & Trends
1. Saskatchewan’s Dominance:
- Defense: The Roughriders’ run defense is unreal (66.5 yards per game allowed, 1st in the CFL). They’ve committed the fewest turnovers (2) and boast a +1.5 turnover margin (2nd).
- Home Field: 5-1 ATS in their last six home games. Trevor Harris, returning from a Week 3 concussion, is 14-4 as a starter at Mosaic Stadium.
- Offense: 28th in pass efficiency (CFL), but their rushing attack (124.3 ypg) keeps defenses honest.
- Calgary’s Weaknesses:
- Air Attack: Vernon Adams Jr. is 2nd-worst in pass efficiency (58.3 rating) and has thrown 4 INTs in 3 games.
- Road Struggles: 2-5 ATS in their last seven road games. They were outgained in time of possession (43.7% vs. 56.3%) in their last win over Winnipeg.
- Rushing Dilemma: Dedrick Mills (5.3 YPC) faces Saskatchewan’s top-ranked run defense.
- Head-to-Head:
- Calgary is 10-6 ATS in the last 16 meetings, but Saskatchewan is 5-1 SU in the last six at Mosaic Stadium.
Injuries & Updates
- Trevor Harris (Saskatchewan QB): Cleared after a Week 3 concussion, but his 2024 stats (14/23 TD/INT ratio) suggest he’s not a vintage passer.
- Vernon Adams Jr. (Calgary QB): Needs to avoid turnovers against a defense that forces 2.8 fumbles per game.
- Calgary’s WRs: No major injuries, but their WR corps ranks 28th in yards per catch (10.1).
Odds Breakdown
Moneyline (via multiple books):
- Saskatchewan: Decimal odds of 1.40–1.44 (implied probability: 69–71%)
- Calgary: Decimal odds of 2.80–3.15 (implied probability: 32–35%)
Spread: Saskatchewan -5.5 (-110), Calgary +5.5 (-110)
Total: 52.5–53.5 (even money)
EV Calculations
1. Underdog Adjustment (CFL = NFL underdog rate of 35%):
- Calgary’s Implied Win Rate: 35.7% (from 2.80 odds)
- Adjusted Win Rate: (35.7% + 35%) / 2 = 35.35%
- EV: Adjusted (35.35%) < Implied (35.7%) → Negative EV for Calgary.
- Favorite Adjustment (Favorite rate = 65%):
- Saskatchewan’s Implied Win Rate: 69.4%
- Adjusted Win Rate: (69.4% + 65%) / 2 = 67.2%
- EV: Adjusted (67.2%) < Implied (69.4%) → Negative EV for Saskatchewan.
Conclusion: The line is priced efficiently per the model. However, team analysis suggests value in Calgary’s underdog role.
Betting Strategy
1. Take Calgary +5.5:
- Despite the EV framework’s neutrality, Calgary’s need to pass (vs. Saskatchewan’s 1st-ranked pass defense) creates a mismatch. Adams’ 2nd-worst pass efficiency (58.3 rating) vs. Saskatchewan’s 1st-ranked pass defense (66.5 YPG allowed) suggests a low-scoring game.
- EV Note: If you trust the model, avoid. If you trust the expert (SportsLine’s Emory Hunt), back Calgary +5.5.
- Under 53.5 Points:
- Saskatchewan’s defense (66.5 YPG allowed) and Calgary’s 2nd-worst pass efficiency (-6.3% DVOA) suggest a dry game. The total has risen to 53.5, but both teams are built for defense.
- Avoid Saskatchewan -5.5:
- Harris’ concussion history and the Stampeders’ ability to force turnovers (2.5 per game) make the spread too steep.
Final Verdict
Pick: Calgary Stampeders +5.5 & Under 53.5
Why: The EV model says “meh,” but the reality is Calgary’s only path to victory is through the air—and that’s a recipe for disaster vs. Saskatchewan’s defense. Take the points and pray for a defensive battle.
Bonus: If you’re feeling spicy, lay the Under. Both teams are built for defense, and this could be the first CFL game of the season with fewer than 40 combined points.
“We’re excited about the challenge.” — Trevor Harris. Yeah, we’re excited about the challenge of watching Calgary’s QB throw a pick-six.
