So I went to the game in Edmonton with the Family and with 4 minutes left in the game, Esk fans start the exodus, lol! My son, 8 yrs old, first ever game, asked why everyone was leaving. Then the Riders make the come-back and all that is left in our whole section is Rider fans! That's when my son figured out Rider Pride and that if it's not a blow-out...you stay till the end!!!
In fairness, you likely wouldnt see a mass exit in a regular season game in the same situation.
Actually Depop....I have seen this before in the regular season. It's quite common.
