That may be true, but they are still the most solid pair so far. Malik and Roszival are awful right now and Tyutin is lost. Pock is that guy we've been waiting for that can jump into the rush and contribute offensively. Pock and Rachunek are the only defensemen right now that realize it isn't illegal for a blueliner to shoot. Positionally they have been pretty sound.
You're right, Malik and Rozsival could take some lessons from them.
