Right now 4th place Edmonton is tied with 2nd place Montreal with 16 “points.”
Edmonton has played 16 games, whereas Montreal has only played 15.
Edmonton has Saskatchewan twice after a bye, while Montreal plays each of the other three East Division teams once.
Of course Edmonton could catch the Riders, and demote them to the crossover. Calgary or Winnipeg could also join the party, if one sweeps the other; creating a three way tie in which case I don’t know all the tiebreakers, but it doesn’t matter because the important part for this excersize is that they’d all have 20 “points” in that case.
Montreal can’t catch Hamilton of course, so they have clinched the 2 spot.
