Haven't read the entire thread so this may have been discussed ad-nauseum already, but HNIC used to be an event, whereas now its just the Saturday night version of hockey on Sportsnet. Started when TSN bought the old theme, and then continued when Rogers cut some of the more unique parts of HNIC (ie Tim Thompson and the CBC branding) and some stuff that wasn't entirely in their control (Cole/Neale and Don Cherry). And in their defense, the sheer amount of games on TV make any individual game less relevant (as a comparative, look at the nostalgic views for NBC's MLB Game of the Week in the '70's compared to the apathy for the Saturday afternoon game on FOX now).
Is it time to get rid of it? I wouldn't go that far - there is some symbolism still in being the featured game in the featured timeslot on network TV. But the HNIC that I grew up with in the '90's/early 2000's is long dead.
