Kadri's played at that level since has grown. It's obvious to me at least. Heck even this year, he should have had 55-60 points. But here's the common thing for the past 2 years:
1) Bad QoT (Grabner literally doesn't know how to put the puck into an empty net)
2) This year at the start he had a Voracek like start (amazing play, bad luck).
3) He's led the 2nd line in points for years, and this year he led the 1st line with points.
I could go on with 'excuses' I guess, but just watching him I can see the results. Under Babcock's possession game, Kadri's playing style fits perfectly.
Don't get me wrong, Couturier is the better player IMO (because I value defensive ability more) but Kadri isn't a 50 point center slouch, he should be a 55-60 point guy this year.
