My crystal ball has the same matchups but I think BC may have to travel to Calgary. You have Cal at 9-9 meaning they lose to Tor & Edm which I don't see. Toronto is on their what 5th string QB? Edmonton is still scrappy but they aren't playing the uninspired Bombers again, and should be eliminated by that point anyway. Calgary probably goes 2-0 to finish at 11-7.
BC has Edm & Sask so they have the tougher match-ups but it may come down to what Sask does with their roster for that last game. If Sask wants all their guys sharp for playoffs then BC has a tough time in Regina. I think BC also goes 2-0 or 1-1. Going 2-0 gets them the WSF but 1-1 may give it to Calgary it so it's going to be a tight race all the way to the end.
