Hamilton & Edmonton are 8-9. So will B.C. be 8-9 if they lose at home to Calgary tonight (Calgary's beaten the Lions twice already this season).
Assuming that the real Alouettes show up this week, Winnipeg will be 7-10 and would host Hamilton for the last game of the regular season, while B.C. plays Edmonton. Possible final outcomes are:
Wpg. 9-9, 8-10 (IN) or 7-11(OUT)
Ham. 9-9 (IN) or 8-10 (OUT - WPG WOULD WIN TIE-BREAKER)
B.C. 10-8, 9-9 (IN) or 8-10 (OUT IF WPG GOES 8-10 or better)
Edm. 9-9 (IN) or 8-10 (OUT IF WPG GOES 8-10 or better)
In summary, it looks like whoever wins the last game of their regular season makes the playoffs. The cross-over rule makes the playoff picture more exciting!
