If history began in 2022 against the Leafs, without the perspective of a decade of watching other postseason collapses, I would agree that it's a problem that needs addressed.
However, we've had a lot of really good offensive teams that couldn't beat tight checking defensive oriented teams. In 2018 we led the league in goals by quite a bit, but we lost the ECF against the Caps by getting shutout in consecutive games. We were offensive juggernauts in 2019, but couldn't manage much of anything against Columbus. 325 goals scored, 100+ goal differential, and we got swept.
We had no idea how to score when the open ice evaporated, and it showed. Cooper was on the verge of being the next Tony Dungy here in Tampa and getting canned. The #FireCooper movement began then.
Yeah, we've collapsed against Toronto, in large part due to Vasy being a liability, but that was an exception. High scoring teams like Boston, Carolina, Florida, the Rangers, couldn't do shit against us. We did to them what Washington under Boudreau and Columbus under Torts did to us.
