One season and a playoff run does not make one a "legit #1 defender". Although maybe you and I have different opinions of what a legit #1 is. I see players such as Nick Lidstrom, Chris Pronger, Sergei Zubov, Andrei Markov, Tomas Kaberle, Dion Phaneuf, Zdeno Chara as legit #1 d-men, players who would be the defensive leader on the majority of NHL teams. Players such as Mattias Ohlund, Michal Rozsival, Dan Hamhuis, Roman Hamrlik and the aforementioned Henrik Tallinder are guys I would consider strong #2's, but wouldn't be the defensive leader on most squads around the NHL.
I guess you are correct in that regard. But then again, that's what separates the "legit #1's" from the rest, consistency.
I agree Tallinders a strong #2 but not a legit #1 D-man.
