Yes, he's technically "improved", but he hasn't made any leaps that show me he will be a top 6 producer. He strikes me as a middle 6 tweener at best. Perhaps he does have some games where he should've been on the scoresheet, literally every player does... But he also has a plethora of games where he wasn't and had no business being on the scoresheet. The latter seems to outnumber the former to a degree that leads me to believe his improvement while existent, is not sufficient.
Even with this top 6 placement, he's produced at exactly the same rate outside of his game yesterday. How does anything about this season (outside the game yesterday) prove that it made a significant difference? I watched his shifts from that game and while he was at the right place at the right time for some decent puck movement and opportunities, he didn't seem dynamic or show an approach to the game that necessarily replicates that type of production over the course of a season.
Unless I've been on a different forum than you completely, I can confidently say I didn't see people disproportionately blaming him for the Rangers series loss. He caught flack and was ridiculed but I didn't see anybody say he was the sole reason they lost that series. The latter would be disproportionate, the former is completely fair. Maybe I didn't dig enough, but the extreme opinions of a select few people don't mean that his performance in the playoffs isn't notably bad and reflective of people's opinions of him.
Mackinnon and Hughes are just two examples but my point still stands. Players that are top 6 or top-line material tend to have elements of their game that shine through, either that or they are moderately skilled in multiple areas and can produce consistently. Like I said, Lafreniere hasn't shown that throughout his career and I didn't see all too much of it yesterday. None of those plays wouldn't have been pulled off by a bottom-six forward. He's a bit faster which contributed to that 2 on 1 goal but he doesn't seem to be any more skilled, just better conditioned. I don't think that's enough to make a player a 1st liner. That's why I mentioned the non linear jump/"everything clicking".
You said he's going to become a top 6 forward, I said that I don't believe so and gave my reasons. That's not creating some false controversy.
