Dubas' biggest mistake was not immediately starting a rebuild and instead trying to maintain being competitive by giving out big UFA deals to Jarry, Graves and Acciari (to a lesser extent) and trading for Karlsson and Smith. That said, we have no clue what mandate he was given from ownership and whether they would have okay'd a rebuild immediately upon starting.
The Penguins collapsed hard in the 2022-2023 season, but remember they were their standard self up until the second half of that season. The Penguins were 9th in the NHL in point% on January 1st and were on track to finish the year with 100 points. They were on track to be 2nd or 3rd in the Metro and be in the same position they had been in for years. In hindsight, it is factually the correct decision that they should have just torn it down and rebuilt them. But at the time, I don't think it was clear the Penguins were as spent as they were in the second half of the 2022-2023 season.
What happened is that the second half 2022-2023 Penguins were the new Penguins, and the only way you could have known that was being able to tell the future. I think an interesting discussion that hasn't happened as much as it should is "why did the Penguins fall off in 2023?", because it was abrupt and pretty out of nowhere.
Nah I think that is very true, especially without major retention. Who else in this league would have traded and given up assets for Karlsson at 10m last summer (trade happened in august btw).
The reasons so few teams would have done it is because the cap wasn't rising much and most teams were strapped for cap space, plus San Jose was just refusing to retain any money. The only reason the Penguins were able to do it was because they moved 3 cap dumps in the trade.
