I'd go with the Karlsson side. Even though Eriksson is off to a rough start, he's consistently a 70ish point player and he's still young. For some reason, I just don't buy into the Seguin hype. Even if he does meet his potential, I think he's going to run at the same point production as Eriksson. Given that, Karlsson > Edler.
