Team Momentum & Stakes
Winnipeg Blue Bombers (3–0, West Division leaders)
The Bombers have stormed out to an undefeated start, winning all three games by double digits. They’re averaging a dominant 32.3 points per game, while allowing just 19.0 points per contest—leading the CFL in scoring defense.
QB Zach Collaros has been sensational, completing 78.2% of his passes for 513 yards, five touchdowns, and zero interceptions over two games, including a 334-yard, three-TD performance last week.
RB Brady Oliveira returns from injury, boosting a ground game that ranks third in the CFL, featuring rookie Matthew Peterson averaging 5.4 YPC.
Calgary Stampeders (2–1, West Division)
Calgary is fresh off a bye but has struggled to find rhythm in the passing game—QB Vernon Adams Jr. has yet to throw a touchdown in three starts, completing just 53% for 218 yards in their Week 3 loss.
Their defense has been respectable overall, allowing around 21–22 points per game, though they’ve been vulnerable to the run—giving up third-most rushing yards in the league.
Offensively, Calgary has a solid ground attack, led by Dedrick Mills, but must find consistency in red-zone and passing efficiency to stay competitive this week.
Key Matchups to Watch
Bombers Offense vs. Stampeders Run Defense: With Oliveira’s return, Winnipeg’s rushing attack could exploit Calgary’s below-par rush defense.
Collaros vs. Adams: While Collaros is firing on all cylinders, Adams needs to break through and throw a touchdown—Calgary’s offensive identity hinges on his passing effectiveness.
Stampede Bowl Feel: This inaugural season matchup, dubbed the “Stampede Bowl,” includes a halftime show with Bret Michaels and local festival flair—but the focus remains on the gridiron rivalry.
Blue Bombers vs. Stampeders Prediction
Winnipeg arrives in Calgary as the more complete team—explosive on offense, stingy on defense, and bolstered by Collaros’s precision and Oliveira’s return. Calgary has home-field advantage and a strong run game, but their aerial attack’s red-zone inefficiency and lack of passing TDs pose real challenges. They’re also 7-3 in their last 10 games against the Stampeders.
