I understand the concern around his skating, but to me it seems like Lundell has that Stepan/Pavelski thing where the stride is awkward and he doesn't seem to have great agility or explosiveness, but lo and behold, there he is lifting a guy's stick at the perfect moment to save a sure-fire tap in goal or suddenly he pops up right next to a yawning net to bury a loose puck - and you wonder how the hell he even got there as you didn't even notice him. You rewind the video back and discover that he didn't watch the play unfold and realize "I should be in that spot", he just innately floated there -he left early so he could be on time.
I actually think he has pretty good top end speed and wonder if his first-step can/will improve once he's done growing. Nevertheless, you can add me to the camp that doesn't think he will be an elite producer in the NHL, because I don't think that is his game - he isn't selfish enough and he doesn't possess any game breaking skills. That being said, I think he can quite reasonably become a top six forward who everyone thinks is good defensively and can produce respectably, but when you do a deep-dive into his numbers you realize "Hoooooly crap, this guy drives play and suppresses chances at an elite level."
How teams selecting in the first round value a player with that upside probably comes down to personal preference and I would imagine the lottery teams who are looking for franchise altering players will probably stay away, but the teams that feel they have offensively gifted young players but lack players that can settle down the entire flow of the game in their favor might value him much higher.
As a a Rangers fan, I'd easily take him if he was available with their first of their two 1st round picks and shoot for a risk/reward player who falls a bit with the other (Gunler/Lapierre/Perrault/Bourque etc.)
