Sadly I'm not a fly on the wall on the Wings bench. But looking at 2019-2020 there was a ludicrous amount of goals within a short timeframe. (Ken Daniels and Mickey commented on how many times Detroit gave up 2 or more goals in 5 minutes or less and it was gross.)
We saw that to a degree this year as well, but not as bad as 2020. A lot of times giving up 2 or more goals within the first 10 minutes of a game. Also giving up 2 or more goals in a 5 or 6 minute span in any period.
We scored 38 first period goals
We let in 51.
Here's the full breakdown of goals by period. I looked at our results for the year and pretty much any game we lost by 3 or more goals saw us giving up 2+ goals in a very short span. I'll try breaking that down later.

This is a good start. And I'm not trying to bust your balls or anything, but when people say a thing is true, I just want to make sure it's not "Hey they commented on it and it feels true" and then we just accept it as fact.
If Blashill's teams are flat out of the gate, as you assert, there should be a way to show his team's 1st periods suck comparatively across the league year after year. He's coached over 450 games now, so we have plenty of data to work with. I'm just curious if this is because the Wings have stunk or if Blashill teams are even worse than other teams that stink.
