Last year he drew 1.38 penalties per 60 at 5v5, this year he's at 3.37
Last year he threw 19.81 hits per 60 at 5v5 this year he's at 18.3, not a significant difference
Last year he got about 55 seconds of PK, this year he's around 2 mins a game
He's giving the puck away about half as much as last year, while keeping about the same rate of takeaways.
He is blocking fewer shots per 60 but that's not always a bad thing.
To me the biggest difference in his game is on the offensive side, he's not getting as many shots through.
Again, I haven't been happy with him, I'd rather Kastelic in the lineup myself.
