As far as the total goes, I'm modeling 49-50 total. So there's not a lot of room to play over 48. Both teams have blowout wins last week (WPG>BC 43-22, CGP>EDM 49-6) but I think this one will be a closer game.
If it's a tight game or if you're leaning towards a CGY will win outright, then the OVER will likely occur.
If you believe WPG will win easily, then the UNDER is in play.
If I had to make a play, I'd go with the over. Going to watch the line and see how it moves closer to gametime.
