Oddly enough I'd feel more comfortable with Iginla at C than Lindstrom. I think he generates offense better from the middle, usually opts to carry the puck through the middle of the ice, and would be excellent at supporting deep in the defensive zone along the boards.
My major knock on him is his skating, but I think a skating coach and some strength training can turn that around within a couple years.
Levshunov is really tough to evaluate. With his work ethic and natural tools he looks like he could be a number 1, but each time I've watched him, I come away thinking he'd be much better as a number 3.
Somewhat ironically, I think you could find some very good stylistic pairing matches with the top 6 D in the draft.
