One thing I find interesting is our record as playoff series enter their second half since the establishment of the core (so 2019). I assigned the "front half" of a series as games 1-4, and the back half of a series as games 5-7. I didn't include 2020 since it doesn't follow the typical format
Front-half record: 7-5
Back-half record: 2-7
So what does this mean? We start strong and look amazing, but as the series goes on we get worse.......a 2-7 record is just abysmal
Why does this happen? Is it the adjustments the opposing coaches make? Is it the other team finds another gear with their season on the line and we don't? Is it goaltending?
It is a lot of things. Our goaltending seems to really shrivel up in high pressure situations (first Andersen, then Campbell), while the other team's seems to rise to occasion. I would say that it is because we don't have a Rask, Price, or Vasilevsky, but we even saw Korpisalo do it for Columbus. We have seen other cheap/unproven goalies do it for successful teams. And we have seen successful or expensive goalies (i.e. Bobrovsky or even Andersen) completely suck. So the answer is not even throwing money or assets at a good or proven goalie.
We get killed by clutch-and-grab, which completely dampens skill and pretty much makes it a "which goalie will give up a crap goal first" fest. Refer to the first paragraph as to why that is not a good thing for us. It is not like it hasn't affected Tampa either; Vasilevsky has won a lot of low scoring games for Tampa. He is just not the goalie who gives up the crap goal first. I don't think coaching adjustments are as big of a deal. A lot of what has killed Keefe especially has been less stuff he (or the other coach) has done and more something where the players mess up/capitalize. He can try mixing and matching all he wants but we have had series where key players could have played against AHLers and they still would have sucked. Successful coaches don't need to deal with that very often.
Finally, we struggle to convert, especially on the PP. Even when we get to the inside, or get chances, we can't put them in. ES is less of an issue. Tampa actually was never a high end ES scoring team either. But on the PP, we really suck at converting and it is not even like things drastically change in the playoffs vs. the regular season when it comes to PP/PK (other than having to go up against better ones more often). Even when we get our setup and our chances, it just looks far too slow and unconfident, and then they start to panic and force things that are not there. It is all mental, and it has happened in the regular season too. Maybe this is where the playoff failures are starting to weigh heavily on them, because it is not like our PP is incapable of producing.
I think there are some things that can be done with the PP. Changing the coach or adding a big shot from the point is not going to do it, but adding more puck movement and speed, and having less isolation is probably a good start. Switch things up sometimes. We can't do anything about clutch-and-grab really, and even become a more "gritty" team doesn't really do much. If teams want to collapse in the inside, then you need to start making them pay with the space you have from the outside or on the rush. We normally do well there, but not well enough in the playoffs. Finally, consider firing Steve Briere. Our goalies clearly have trouble with certain fundamental skills, consistency, and mental toughness. He is responsible for a lot of that, and with a new starter coming in, now is the best time to make that change. He is also the only coach to still be here from the beginning of our failed runs (before Dubas and Keefe), and goaltending has been at the forefront of those failures. If we are talking about a change that actually makes some sense, that is probably #1 on the list by a long shot.
