It looks like he is 12th among RW in A60 for the last 3 years behind players like Garland, Konecny and Zuccarello and there are 16 LW ahead of him including guys like Barabanov and Marchment so I would say probably not accurate. Its clear you have a deep and abiding hatred for Tavares but guys like Kaprizov and Panarin were having better seasons than Willie stapled to Hartman and PLD. If Willie had a more talented center he could likely score a bit more but an 87 point guy can't really be dragged down much by an 80 point guy or at least many forwards have great years even with sub 70 point linemates. I think this is what Willie is and he thrives in the usage he gets. Mark Scheifele is not more productive than JT and he plays almost 3 minutes more a night. Connor > Willie.
First, it was passing, not assists, and the other discussion was about two years, not three, and the stat about passing was about last year.
But even just looking at 5v5 assists/60 (your criteria) and only players who played at least half the games:
Last three years, Willy 13th among RW in assists.
Last two years, Willy 13th.
Last year, Willy 10th.
Who was he playing with?
Last three years JT was 47th among C in goals.
Last two years JT 47th
Last year 38th
And nobody particularly good on LW.
You can't talk about 5v5 per 60 and at the same time talk about JT getting 80 points. JT had 16 goals at 5v5 last year, and was tied with Engvall for fifth in g/60. (Willy had 27 assists at 5v5, behind only Mitch in total and a/60.)
I don't hate JT (I don't like his contract, but I don't blame him for it), but I can see, as is supported by the stats, that he is not a good fit with Willy. The fact that they have had a constantly changing collection of mediocre left wingers hasn't helped.
"Scheifele is not more productive than JT." Last year he had 25 goals at 5v5 (JT had 16) and was 14th in g/60 among centres (JT was 38th).
