I disagree. Not sure how it's much different from when there's been a sold-out Blue Jays game, a sold-out concert at ACC, and a full stadium at BMO Field - which has happened before.
It will come down to which timeslots have the biggest potential US TV audience, and which game will attract the most viewers. As there is no baseball on Thursday October 28, I suspect the biggest match-ups will be on that day. What might work in our favour, is that Bradley and Altidore might get more TV interest than Columbus Crew or Sporting Kansas. Though if Montreal plays Toronto, I'd think Wednesday.
