1. Calgary Stampeders
You can't really argue with 12 and 3. They've done it with a combination of different quarterbacks, which even strengthens their power ranking as they are more resilient to the traditional bugaboo of a good football team, starting quarterback injury. They've still been successful without receiver Nik Lewis as well, but having Jon Cornish as your starting running back means the passing game isn't as important. Throw in an excellent front defensive four and you have a team that wins a lot.
2. Saskatchewan Roughriders
The Riders are a far better team now that running back Kory Sheets is healthy. Without him, quarterback Darian Durrant is mediocre, with him, he's significantly better as is the entire team. Sure the Riders barely managed to beat the Eskimos, but good teams are going to win close games occasionally rather than blowing out teams every week. The Riders certainly aren't looking as invincible as earlier in the season.
3. Hamilton Tiger-Cats
The Cats have won two straight over their arch rivals, the Toronto Argonauts and now have a chance at winning the East overall. The Cats have basically the only elite quarterback who has started all year (sorry Mike Reilly) and so many quality receivers that injuries don't matter. C. J. Gable is emerging as one of the better backs in the CFL and is arguably the best at receiving. The defence is no longer terrible either as they were earlier in the season.
4. Toronto Argonauts
Strangely the Argos were on top of the world, winning four straight on the road against some of the CFL's best teams without starting quarterback Ricky Ray. Then they played two games against the Ticats and lost both. Ricky Ray was back in the last game and was good statwise, but still had a bit of rust. Likely after playing a game, Ray will be better this week, plus the Argos still have a solid defence (although that wasn't evident in the last two games).
5. BC Lions
Uh, is Travis Lulay coming back? DeMarco is OK as a quarterback, but at this point in the season he's not good enough yet to compete with the best teams in the league. Andrew Harris is having a good season, but not as good as last year. The rest of the Lion receivers are kind of meh. The defence is still respectable, but if the Lions want to do anything in the playoffs, Lulay will have to come back and play well.
6. Montreal Alouettes
By losing to the lowly Bombers at home and the Ticats winning, the Alouettes have pretty much crapped the bed at their chance to catch Hamilton and have a home playoff game. Now they have to not totally suck to hold off the semi-surging Blue Bombers for the last playoff spot in the East. Kind of embarrassing, but that's what happens when Anthony Calvillo's head is scrambled.
7. Winnipeg Blue Bombers
With a win, the Bombers are firmly out of the basement of the power rankings. Beating the Alouettes at home almost warrants the Bombers up a further spot, but they've only won three games in 2013, which obviously isn't much. Is Hall the real deal in Winnipeg at the quarterback position? Who knows. However their offense didn't suck enough to trash a good outing by their defence so maybe there's hope for next year.
8. Edmonton Eskimos
The Eskimos lost yet another close game, this one on the road to Saskatchewan. Edmonton has had some moral victories, but not a lot of victories. Will Kavis Reed get the boot at the end of the year? Probably. Will Edmonton lose out the season. Probably.
