Good question. I mean obviously Rangers fans are attracted partly because he does fit a lot of team needs.
But, let's put that aside for a second and look at the player.
He's an incredibly smart player who plays a game that looks like it could translate very well to the NHL. He's not skills competition prospect who is out there dangling around a 16 year old defenseman and handing him his lunch.
He's calculated and efficient and effective. He find the open guy, makes the high probability play, and sees the ice very well. He's capable of beating goalies with his shot, though he probably needs to use it more. But he's always in the middle of a play and usually makes things happen.
When I see Lundell, I see a kid with a high probablity to play center in the NHL. The only question is how high the offense will be. Some people think he might be more a 2/3 center. Personally, I think his potential is on the higher end of the second line tier. I know a few teams that view him as more of a 1A/B type not all that different from the level a prime Brassard and Stepan hit.
But he's one of those guys who plays a game that has a clear trajectory to the NHL. You can see how his game works and it's not hard to imagine it working in the NHL --- because it revolves around vision and hockey sense.
