The 104th Grey Cup is this Sunday (6 PM ET, ESPN2), live from BMO Field in Toronto, and on paper, it looks like a mismatch between the Calgary Stampeders and the Ottawa RedBlacks. The Stampeders opened as 9-point favorites with a total of 54.5 before moving to –9.5.

The Calgary Stampeders (16-2-1 SU, 14-5 ATS) are 9.5-point favorites for Sunday's Grey Cup game against the Ottawa RedBlacks (9-9-1 SU, 8-11 ATS), kicking off from Toronto's BMO Field at 6 PM ET on ESPN2. The total opened at 54.5 points on the CFL odds board.

Calgary (16-2-1 SU, 14-5 ATS) deserve to be the favorites after rolling over the rest of the CFL. The RedBlacks (9-9-1 SU, 8-11 ATS) aren't as strong as last year's Grey Cup finalists, and they're only 1-5 SU and ATS versus the Stamps since bringing football back to Ottawa in 2014.The over went 4-1-1 during those six games.

As well as the Stampeders have played this year, the RedBlacks remain a viable threat. They beat the spread in last year's 26-20 loss to Edmonton, cashing in as 7-point underdogs. Also, Calgary failed to cover two years ago in their Grey Cup win over Hamilton (+7.5), winning a close one 20-16. Both those games went under.

Sunday's weather forecast calls for partly cloudy skies over Toronto and temperatures in the low 40s – or around five degrees Celsius.
