After overcoming an injury to Chad Kelly in the CFL playoffs last year and winning it all behind the arm of backup Nick Arbuckle, the Toronto Argonauts are the favorites to repeat as CFL champions by the Grey Cup odds at the best sportsbooks in Canada.

The Argos' biggest competition coming into the season is the Montreal Alouettes, who were the favorites to win it all for much of last year and traded starting QB Cody Fajardo in the offseason. Trailing those two are the Winnipeg Blue Bombers, who have played in five straight Grey Cups but have lost three consecutively.

🏈 Resilient team performance: Despite facing challenges in the previous season, including injuries, the Argonauts demonstrated depth and resilience, culminating in a Grey Cup victory
🏈 Consistent coaching and management: Head coach Ryan Dinwiddie has effectively guided the team, and the front office has made strategic acquisitions to strengthen the roster

🤔 Betting takeaway: ChatGPT's AI prediction would mean the Toronto Argonauts (+325) repeating as Grey Cup champions. ChatGPT is a large language model and not specifically designed for predicting sporting events, so these projections should be viewed as entertainment or a supplementary data point for your CFL championship betting research.
