Zamula provided an assist and went minus-2 in Wednesday's 6-3 loss to the Capitals.
Zamula has two assists and a minus-10 rating through seven contests, and his defensive struggles could eventually cost him a spot in the lineup. The defenseman has added seven shots on net, six hits and 12 blocked shots. He's seen power-play time but plays on the third pairing at even strength, though head coach John Tortorella may get more reliable defense from veteran Erik Johnson.
