Well, like it or not, the RedBlacks ARE an expansion team.
I expect they'll be the CFL doormats for at least 3 seasons, maybe more.
Will the fan base still find it fun at TD Place stadium long enough to see a winner?
The problem is, if you want a good football team, you have to be willing to support them through the awful expansion phase. The Renegades didn't even last long enough to become a really good team.
For them to exist in 3-5 years, they have to be some what viable right now. I'm sure the owners have some idea of what to expect through out the first few years when the team sucks, but the bottom line is, if there's not a big enough demand for football that would allow enough fans to buy jerseys and watch games when the product stinks, then the team will eventually cease to exist.
I think the Redblacks will find a way to market the experience of games beyond "come see our team win", and they'll be fine. But this is Ottawa, so I also would not be surprised to see the team fold a few seasons in if they can't win.
Right now, it's not so much the losing, but how awful a majority of the Redblack's games have been. It's just not a fun product to watch most of the time.
