I honestly haven't watched any Preds games but I was wondering what's up with PK Subban these days. He's playing 25+ minutes a night in the WCF so I assume he's been pretty good but he's scoring #'s are a bit disappointing by his standards and he's being a couple off-brand defensemen on his own team (bare in mind Subban has a Norris and $70 million contract). He's also taking about half as many penalties (54 vs 106 last year) which more than makes up for the reduced offense ( that's 10 goals against a 20% PP). Did he just become a more mature/risk adverse player overnight when he got traded or is there something else going on?
No.
People just made up their mind that he was a very risky player back in Montréal when it wasn't quite true even back then.
He didn't change overnight. He lost some footspeed over the years and hasn't really rushed the puck like he used to as a result. The last time Subban played a very offensively oriented game was back in 12-13 when he won the Norris. Beyond that, Therrien sort of put his stamp on him and had him play a much more conservative style, which still earned him a Norris nod in 14-15.
PK had to deal with a few injuries since last season and he may not be at a 100%, or at least he certainly wasn't earlier in the season. That, and also the fact he probably had to get over Montréal at some point and turn the page. His play improved gradually and he generally ended the season on a strong note and he has been a beast in the playoffs as well.
I'd expect a strong year from him next season.
