I expect Kadri, Huberdeau, and Weegar to have a better second half. Given what we saw with Gaudreau and Tkachuk in the first season drop off that they had when Sutter came on in Calgary, plus with Zadorov having said that it took him about 40 games or so to get comfortable with the new way to play.
Additionally, Kadri was stuck playing with Dube and Mangiapane on a line that didn't quite work for a lot of the first half. He's with a top end player in Huberdeau who has figured things out to some extent and hopefully they will get another winger that fits and can score.
Adding to that, the Flames offense at 5v5 has picked up over the past 10 games (Ryan Pike put together a review of the first 40 games here
https://flamesnation.ca/news/how-do-...after-40-games ).
Personally my grades would be (combination of performance, production, expectations, and role):
Huberdeau: D
Kadri: B
Lindholm: B
Toffoli: A
Dube: B
Mangiapane: D
Backlund: A
Coleman: B
Lucic: D
Ruzicka: B
Lewis: C
Ritchie: C
Rooney: F
Tanev: A
Zadorov: A
Andersson: B
Hanifin: B
Weegar: C
Stone: B
Mackey: D
Markstrom: C
Vladar: A
