Argos have been pwned repeatedly all season by the Cats. This is a win, maybe not as easy as before but a win. I'm already looking ahead to the other games and counting chickens before they've hatched.

I'd say it's 4. i.e. 2 Ti-Cats wins & 2 Argo losses in the next two weeks would mean the Cats have 18 pts., Argos 14 and, with then only 2 games remaining for each team, the most the Argos could have at season's end is 18 (and the Cat's have the tie-breaker based on their 2 wins already over Toronto).

Keep the faith, Big Al. Hope you're right!
