Ottawa Redblacks vs Calgary Stampeders Preview

Ottawa’s record is impossible to ignore, but the quarterback change creates a different handicap than the one attached to the first 12 games. McLeod Bethel-Thompson will make his first start of the season after providing a spark in relief against Toronto.

Bethel-Thompson completed 16 of 23 passes for 192 yards and a touchdown in the 26-23 loss. That performance did not fix Ottawa’s structural problems, but it gave the offense better rhythm and more efficient distribution than it had shown for much of the season.

The Redblacks remain last in several defensive categories. They have allowed 36.6 points and more than 450 yards per game, while opponents have converted second down at an extremely high rate. That makes Calgary’s offensive matchup attractive even after two ugly losses.

Vernon Adams Jr. remains the clear quarterback advantage. He has 25 touchdown passes this season and owns a 6-2 career record against Ottawa. Calgary’s offense has been at its best when Adams is protected well enough to extend plays and use his mobility outside the pocket.

The problem is everything around the quarterback. Calgary allowed 91 points in its two-game set against Edmonton and lost the rematch 53-16. Adams completed only 10 of 19 passes for 142 yards with one touchdown and two interceptions before Josh Love finished the game.

Calgary’s defense has also made it difficult to protect large spreads. The Stampeders have allowed more than 400 yards per game and have been vulnerable through the air, which creates a plausible path for Bethel-Thompson to keep Ottawa within striking distance even if Calgary controls the game.

Matchup Breakdown

Calgary’s best offensive path is to attack Ottawa on first down. The Redblacks have struggled to stop both the run and pass, and that has repeatedly left opponents in favorable second-and-short situations.

Ottawa’s opportunity comes through Calgary’s secondary. Bethel-Thompson does not need to turn the Redblacks into an elite offense. He needs to create enough completions on time to produce three or four scoring drives and prevent Calgary from building a double-digit cushion.

Calgary has also struggled late in close games. The Stampeders are 2-7 in games decided in the final three minutes and 0-4 in games decided by four points or fewer. Those records do not directly predict this matchup, but they reinforce the idea that Calgary has not been comfortable protecting margins.

Ottawa is 4-8 ATS despite its 0-12 straight-up record, while Calgary is 5-8 ATS. The spread therefore requires a distinction between winning the game and covering more than a touchdown. Calgary is the more likely winner, but the Redblacks have enough new quarterback upside to make +8.5 attractive.

Weather should favor offense. Calgary is forecast for sunshine and a high near 23 degrees, with clear conditions into the evening. There is no meaningful rain or wind concern currently built into the game.

The total is 62.5, which is high but justified by both defenses. Ottawa has allowed repeated explosive performances, while Calgary has allowed 91 points across its past two games. A competitive Ottawa offense would create a direct path to the Over.

Game Thesis: Calgary has the superior quarterback and should win at home, but laying more than a touchdown with a defense that has struggled to protect margins is difficult. Bethel-Thompson gives Ottawa a more experienced distributor and a realistic path to the high 20s. That is enough to support the underdog and a game that can reach the mid-60s.

Ottawa Redblacks vs Calgary Stampeders Best Bet - Spread: Ottawa +8.5 (-110)

Ottawa +8.5 is the best bet because the wager does not require the Redblacks to win. Calgary can control the game and still fail to cover if Bethel-Thompson produces a more functional passing offense.

The quarterback switch matters most on second down. Ottawa has repeatedly put itself into obvious passing situations, but Bethel-Thompson’s experience gives the offense a better chance to distribute quickly against a Calgary secondary allowing significant production.

The number is critical. Ottawa +8.5 is playable, while +7 would remove much of the value. Bettors should avoid chasing the underdog if the market falls through a full converted touchdown.

Ottawa Redblacks vs Calgary Stampeders Total Pick: Over 62.5 (-110)

The Over is the preferred secondary market because both defenses create scoring opportunities. Ottawa has allowed more than 36 points per game, and Calgary has surrendered 91 points over its past two contests.

Bethel-Thompson does not need a perfect first start. If Ottawa reaches the high 20s, Calgary can do enough against the league’s weakest defensive profile to push the game above 62.5.

The clear weather forecast removes another potential obstacle. There is no current reason to expect precipitation to suppress either passing game.

A 35-29 Calgary win produces 64 points while keeping Ottawa inside +8.5.

Prediction: Calgary Stampeders 35, Ottawa Redblacks 29
