Your entire post is just an incoherent strawman.
1) He's not ready for the NHL? Name the last #1 overall drafted forward who DIDN'T PLAY the very next NHL Season that transpired. This is laughable, he is absolutely ready to contribute at the NHL level, it's rare for #1 overall D not to play, it's essentially unheard of for forwards in the modern day NHL.
2) Literally nobody is saying he's Crosby or McDavid, but he's also objectively better than Lafreniere who he was more productive then in a lower scoring league a full 14 months of development younger...this is just silly.
3) Him going to NCAA to play against men and challenge himself is a positive, not a negative. He could've scored 200 points this season in the W, but he was already CHL player of the year and won the WHL Championship....I love the drive, willingness to challenge himself, also absolutely loved the adjustments he made in the second half.
4) RE : Lafreniere, this is just subjective nonsense that's not going to go anywhere. Lafreniere had one gear, I was a big fan of his but he was the worst skating #1 overall forward since Tavares, he could never shift gears the way a player like McKenna can, he also didn't have anywhere near the vision, hands. Comparing the statistics of a 16 year old to a player nearly 15 months older is just absurd, whether Lafreniere was viewed as an elite prospect or "very good" is completely and totally irrelevant, McKenna as a 16 year old was better and more dominant than Lafreniere in his Draft year in a lower scoring league, McKenna was undersized playing NCAA in his draft season, Lafreniere was significantly larger than the average Q player at 6'1 195 lbs.
I've seen both of these players life numerous times(Lafreniere around 10 times) and it's very, very evident you never spent time watching him in the Q.
Regarding Celebrini -- No, I used him as an example for just how good, productive Gavin McKenna was in the NCAA at generating scoring chances, literally nobody said this....but absolutely nobody in 2024 thought Celebrini would be the most dominant teenager to enter the NHL since Sidney Crosby either.
