Most heartbreaking losses in Argos history?

[doubleblue]

Not sure about heartbreaking here, but the Argos lost a weird late season game in 1983 to the Ottawa Rough Riders. It was definitely an upset. The strange part was with the Argos trailing 20-19, Hank Ilesic would miss a go ahead FG, but the ball would travel through the end zone to presumably tie the game at 20. The scoreboard clock read 20-20, but the minutes later it would change back to 20-19 for Ottawa. It was determined that Ilesic's FG attempt skimmed the upright, which resulted in a dead ball. This was not announced in stadium until very late, perhaps even as the game ended.

Strange, and in a way, heartbreaking.

I never did like that rule. But I think I am coming into the "eliminate the single point on missed field goals", camp.
