Unless they work out a deal to air some games on CTV, or cross promote effectively.The big downside is that exposure will be down. It's not just the airwaves, but on basic cable as well.
Still, I'll take my chances. Over the last 15 years, nearly every MLB, NBA, and NHL Team has taken their ball here in the States to a regional cable outlet. The Detroit Red Wings air their games, almost all of them, on Fox Sports Detroit. When they're good enough, they win the night, beating out most network programming on traditional over-air broadcast. I don't think, over the long term, it has really hurt exposure to the sport.
