The Sabres are bad example to compare the Bills too. They have strong ownership now, seemingly, a dedication to winning and they have had a few winning seasons as of late.
The Bills have been an absolute joke for 13 straight years from the top down. If the Sabres had that long a series of futility, the HSBC would be empty too and they'd start playing games in Hamilton.
Again, this failure in TO has less to do with it being in TO and more with the Bills being a horrible, horrible football team with no national respect. If the Bills were good, the SkyDome would be filled with bandwagoning Torontonians cheering for them.
Instead, they're pretty much a farm team that better teams beat up on.
