I have to take some issue with the notion that he was a high IQ player.
Eric came into the league used to the idea that he could be a bull in a china shop and get away with it. He was a man child among boys while in the OHL. He came into the league with a great package of size and skill but was either comically unaware of what was going on around him, didn't care, or thought he was invincible.
This is ridiculous. Eric Lindros without hockey IQ was Brett Lindros. You can't say that a guy who is top 10 all time fastest to 600 points isn't high IQ.
Did this project (with some help) a while back on another forum to collect the complete lists of players reaching 100 point, 200 point etc. milestones while being atleast PPG pace at the milestone. Former NHL records are indicated by * and the date (day.month.year) when the milestone was...

The stories and myths around Lindros are absurd.
He was just big boy genetics attached to the typical first overall package. Not close to generational at all. If that's the case, then Jagr must be generational too (he's not).
Look at the HF thread above. The stories and myths are absurd because his peak was absurd (albeit short). Lindros collecting points while playing the way he did in his first 500 or so NHL games while never being fully healthy was just nuts. That being said, there's a bunch of guys who were the same and are on that list even though they too were never at 100% health (ie: Crosby, Lemieux, Orr etc.) so maybe that's just par for the course.
Based on your Jagr mention, Jagr begins to surge past Lindros at around the 800 point mark due to him maintaining a high calibre of play throughout his career and the unreal longevity/health/fitness he had in his late career.
Lindros real accomplishments cement him up there as one of the best to ever play the game. That's objective. There's no myth to that. It's not projections.
Lindros wasn't just a big boy in a first overall package. He had even more. Top 5 strength for all guys who have ever played the game. Top 5 meanness and nastiness than all guys who have ever played the game without being considered a head hunter or lunatic that liked hurting people.
Byfuglien's physical dominance mention was a good one. Big Buff is the last guy in recent memory that was big and strong enough to occasionally go around rag dolling multiple people like Lindros did. But he didn't have the same mean streak and hockey skill set as Lindros.
Pronger IIRC is up there for dominating skills, size and mean streak. But I don't recall Pronger having the same strength as Buff and Lindros to rag doll dudes in the same way. I remember when I was younger thinking that Eric's stick mechanics looked weird. I double checked the other night and it's just weird to see some of his shots look like they have baseball or tennis swing mechanics mixed in. The strength was unreal.
As mentioned by another poster, few shed tears when his career ended. He was an absolute monster plain and simple. Reread the comments and many previous threads. Lots of the descriptions of Eric Lindros aren't celebrations of his dominance. It's more like campfire stories of a monstrous beast unleashed upon the league that terrorized their favourite teams and players. There's certainly a lot of intrigue as time goes on, but honestly speaking, I think most non-Flyer fans that remember him are kinda glad he's gone and another has not shown up and may never show up.
