The swing and a miss is from you friend. I said scoring chance generation. At 5v5, SEA was 20th in xGF/60 in 22/23, per Evolving Hockey. 22nd in scoring chances for/60, per NST. They don't create chances well. Which is exactly what I said.
The misunderstanding is from you not being able to distinguish results and the chance creation process. SEA was first league-wide in 5v5 shooting percentage in 22/23, at 10.4%. That was simply not repeatable, more the result of good fortune. They were at 8.2% in 21/22, and 7.7% in 23/24. Hmm, which one is the outlier here?
I was exactly correct. Hakstol teams don't generate much offense. He was the beneficiary of fortunate finishing in 22/23, which was not going to repeat itself. I had quite large positions against SEA this season (under point total, miss playoffs, and a very juicy H2H bet with VAN) for this reason.
