Least Watched Pre-Season Game Ever?

The CFL pre-season kicks off tonight with BC at Calgary, starting at 9 pm EST. The first ever pre-season game broadcast on TSN (OK there was a Touchdown Atlantic pre-season game in Halifax a few years ago, but that was a special event) is going up against the Vancouver Boston Stanley Cup game 7. I'm guessing the folks at TSN might have preferred for the Canucks to have won game 6 so they would have tonight to themselves, but things happen. I suppose if Boston has another monster first period, TSN may get a few people switching back and forth, but this is going to be a low rated game.
