If it was any other poster, you'd agree it's weird. I've had The Instigators on, mostly on mute, and there also hasn't been anything on the screen indicating a presser. (Yes, I know it's happening.)
It's either being kept deliberately quiet, which makes no sense, really, or it's an indication of how much the Sabres take their fans for granted and have little interest in growing their fan base (or, you could argue, putting a decent team on the ice in the short term). Like, Sabres fans will find out... somehow. They've got MSG or WGR on 24/7.
