I second this. Wiercioch needs an offensive defenseman to compliment him properly. Look at his WOWY's when he played with Gonchar in the short season. Good sample size too.
He also has respectable numbers with Cowen (71.4%GF, 50.8%CF, 159:52 5vs5mins), Benoit (66.7%GF, 53%CF 106:04 mins)), Ceci (53.8%GF, 50.4%CF 129:26mins), Karlsson (88.9%GF, 63.1%CF, 72:52 mins), and Methot (66.7%GF, 52.1%CF, 47:15 mins) and even David Hale (50GF%, 56.2%CF, 47:35 mins)
I don't think it matter what type of player we pair him with; though he seems to have little chemistry with Phillips or Gryba.
In fact, playing with one of Karlsson, Ceci, Methot, or Cowen (ie playing with players still on the team not named Gryba or Phillips), he has a 64%GF and 53.1% CF in 409.42 mins of icetime (though they were a bit sheltered).
