"Management (at The Score) is seeking an edgier, in-your-face attitude to its on-air product. One insider called it a MuchMusic style for sports."
-- William Houston, globesports.com
There's the Houston article from Tuesday's Globe & Mail referenced in the comments down below for anyone who hasn't seen it. Again, it's very early in the game to know what this means with regard to The Score's CIS coverage, but the question should be kept out there.
Personal opinion is that The Score will be chasing a demographic it's never going to catch if it goes through with these changes. Sports viewers want to be entertained, but also have an element of just-the-facts-ma'am. The Score always has more information than the other two networks, and you can usually get it quicker than on the other networks, especially if your horizons as a fan extend beyond the NHL.
Bottom line: If people wanted MuchMusic, they'd watch MuchMusic, and I can't remember the last time I did.
