The focus for the Boston Bruins of late has been the absence of defenseman Zdeno Chara, but perhaps it should instead be on the absence of David Krejci.

The center has missed the past six games with an undisclosed injury, and the Bruins’ offense has taken a hit as a result. The B’s are 7-7-1 without Krejci, and their goals per game dropped from 3.2 with him to 1.7 without.

Not to mention, fellow center Patrice Bergeron’s production has declined with his increased workload.

“I think, at times, he’s putting so much pressure on himself,” NESN’s Billy Jaffe said before the Bruins’ matchup with the San Jose Sharks on Thursday. “So much pressure to make a difference without Krejci and Chara in the lineup, and these guys are so cool, calm and collected on the outside, I can’t imagine that Bergeron isn’t feeling it a little bit internally, trying to score and trying to be the leader.”
