People outside Ontario don't hate the Leafs because the local media is toxic. We don't really care, shit like that happens in Vancouver, Montreal, New York too and I'm assuming probably places like Ottawa, Alberta, Chicago, Detroit and any other hockey-focused market. Has a lot more to do with the national media (TSN, SNET, HNIC) that is supposedly NATIONAL focuses so much on Toronto-based sports. Not just the Leafs, but Raptors and Jays too.
Back in the day when Sportsnet's nightly highlight show was localized we'd still often get Leafs/Raptors/Jays highlights before the local team of any sport.
