Argonauts vs. Stampeders Prediction & Odds: CFL Week 20 Expert Picks & Best Bets

Last Updated: October 17, 2025 4:06 PM EDT β’ 3 minute read X Social Google News Link

My Argonauts vs. Stampeders prediction features a play on the spread, along with a player prop bet.
The Stampeders are listed as a 9.5-point betting favorite on Saturday. My CFL picks break down this line and take advantage of a misconception in the market. Kickoff from McMahon Stadium in Calgary, Alberta, is set for 7 p.m. ET (TSN/CFL+). My CFL prediction fades the favorite and includes a +180 anytime TD scorer afterward.

CFL expert picks for Saturday; odds subject to change.
- Game prediction: Argonauts +9.5 (-108 via DraftKings) βββββ

π Who will win Argonauts vs. Stampeders?
The Stampeders are a -470 moneyline favorite over the Argonauts (+375), and while Calgary will probably win, there's nothing wrong with taking a shot with Toronto at this price.
The home favorite is being overvalued in this game. However, the safer play is to take the points with the Argonauts instead of the implied probability of 21.05% on the +375 moneyline odds.
Prediction: Argonauts 24, Stampeders 22
β Argonauts vs. Stampeders expert pick
β Argonauts +9.5 (-108) βββββ
The Stampeders will clinch a postseason berth if the Winnipeg Blue Bombers or Edmonton Elks lose on Friday. While the Blue Bombers are a 7.5-point betting favorite over the Saskatchewan Roughriders, the Elks are a 6.5-point underdog and will likely lose at the BC Lions.
So grab the value with Argonauts +9.5 (-108), as this line will likely drop if Calgary clinches a postseason berth on Friday. While Toronto technically has nothing left to play for, it is still playing for pride. In a playoff-clinching game for the Roughriders in Week 19, the Argonauts were competitive and covered as a 10.5-point underdog in an 8-point loss.
DraftKings has the best odds available at the time of publish. These -108 odds to bet Argonauts +9.5 feature an implied probability of 51.92%, and a winning $10 bet would profit $9.25.

π₯Deonta McMahon anytime TD scorer (+180) ββββ
Deonta McMahon will be the starting running back on Saturday. When he has carried the ball seven or more times in a game this season, he has gone 1-1 as an anytime touchdown scorer.
With QB Jarret Doege throwing for just four touchdowns and six interceptions this season, look for the Argonauts to rely on the running game and, in turn, give McMahon a much better chance of finding the end zone than these +180 odds suggest.
The best odds available at time of publish for McMahon to score a touchdown are +180 at bet365. A winning $10 bet would profit $18 with an implied probability of 35.71%.
