Yes, during the first record setting period of offensive production since the 2004-05 rule changes that start PP's in the offensive zone.
You can't really compare PP efficiency before 04-05 under old rules and in lower scoring times to today for any meaningful comparison. The game today is very different than 10 years ago, is extremely different from 20 years ago. It wasn't all that long ago, 20% was considered one of the best PP's in the league. '96 Red Wings won 62 games when the league had ties and scored 325 goals, and were only 21.1% on the PP. 1996 Penguins were at ~26% with Lemieux, Jagr, and Ron Francis basically playing on the same unit with Zubov at the point. 1993 and 2006, the two years the league "exploded" offensively (relatively), league average PP was 19.5% and 17.68% respectively. Last year's league average PP was 21.3%. This year it's still over 20. Powerplay rates across the league are at generational highs.
Trocheck wasn't there two years ago so the unit was different then.
So it's really one season (2022-23) being pointed to by everyone who hates the idea of trying something different, and that also just happened to coincide with Laf's worst season as a pro, possibly the worst season of his life. And now he's having his best NHL season by far, and is putting up great even strength metrics and is driving play. What exactly is that giving up? The three guys that drive the PP are still out there in comfortable spots to them, and our top faceoff man is still taking the opening draw and in the bumper.
OTOH, I don't understand the love affair with Mika this year. He's been pretty bad. Laf, on the other hand, is having his best season by far, and is dangerous with the puck in the offensive zone. Mika gives you the slap pass to Kreider which has not worked this year, and the one-timer which has worked 3 times in a calendar year. Other than that, he's not doing anything that any decent skater with an NHL shot can't do out there. He finishes setups he shouldn't miss, and sometimes someone buries his rebound or he dishes to Fox or Panarin who make a play. Once in a while he finds Kreider netmouth. He's not winning board battles. He's not recovering the puck like a champ. He's not shooting exceptionally well. It's not like I'm suggesting putting Bonino out there or something, or putting Fox in front of the net and Kreider at the point.
