David Krejci worked on the point with Zdeno Chara on Boston's top power-play unit on Monday. He was worked from that spot before with Pardubice during the lockout and when he played junior, but he hasn't been tried there by the Bruins until now. "We try to have more options," said Krejci, who alternated with Rich Peverley during the session. "We don't want to be sitting with one guy making plays. I think we have better looks and more options from both sides. If me or Pevs are on the point on that side, it's going to be more difficult on penalty killers."
