3rd best in points? He's tied with Rants who missed 13 games so no.
3rd best in effort? Certainly not
3rd best defensively? nope.
3rd best in his role? nope.
So...was he our 3rd best forward? No.
He is tied with Rants for second in points as a forward. So yes, he is 3rd in points because Rants did it in fewer games.
For effort, I would put him in a clump in the middle. A few for sure above him, a few clearly below, but a bunch that could go either way, depending on recency bias.
Defensively, not sure he has been worse than a couple of the ones he is supposed to be worse than. But the ones that have been for sure better are mostly a BIG step down offensively.
Who has been a better 2nd line winger? That is his role. And he has done as well in that role as pretty much any other forward on the team in their respective roles...MacK, Calvert and Nuke are it for ones I consider to have been better in their roles. I could see arguments for PEB and Donk. While Rants is better, he has not been performing as well in his role ($9M+ winger) as Bura has as 2LW. Landy has been rather poor this year overall, and especially in his role as 1LW. Jost, JTC, and Neito have not.
Adding talent into the mix, I would put him as 4th, roughly in line with Kadri and Landy (now).
If you were to rank the forwards in those categories, would be interesting to see where they come out when you sum them. For giggles, I tried it. Using my subjective rankings/groupings, Bura came in a four way tie for 2nd with Rants, Donk, and Calvert. MacK was clear #1, Jost was 12th by a hair (Nieto).
Full order: Mack....... (Bura/Rants/Donk/Calvert). Kadri. Nuke, PEB... JTC, Landy... Neito, Jost.
