Haven't gone through the whole thread so forgive me if this was covered but didn't Colorado lose a series because of a goal called back (or they gave one up on a PP because of) when Landeskog (I think it was him) didn't get off the ice fast enough on a line change? Think this was 2019.
Anyway, it was a nit picky call on a play that happens all the time like Bednar says. I recall the Avs being pretty unhappy at the time. They must be feeling pretty smug right now.
