When he mentions needing the minor league hockey/baseball approach targeting groups sales, the only relevant example I can think of would be the Marlies. I don't pay much attention to them, but I was under the impression that they've usually had only small crowds except for 2 or 3 times a year when they have 11 a.m. weekday games and arrange for a few thousand school kids to be there.

I don't understand how that could apply to the Argos, since it's not realistic to suggest having a weekday game start at 11 a.m.!
