PHILADELPHIA — All of a sudden the Bruins are missing 89 points of production out of their lineup.
This is not a team that has all that much production to lose, let alone almost 100 points. Marco Sturm  (22 goals, 15 assists) may not be seen as a huge loss for Boston, as he had not scored a goal in the playoffs and only had two strikes since March 13, but the loss of David Krejci  (17 goals, 35 assists) to a reportedly broken wrist after a hit from Flyers captain Mike Richards  in Game 3 is a huge blow.
Krejci was the key player to spur the Bruins to their late-season run and has been instrumental in their playoff success. It took the young Czech center a while to get going this year coming off of offseason hip surgery but he has been near the top of his game since the Olympic break, constantly creating chances around the net and showing that he has the potential to be a top-tier offensive talent in the league. He can be a joy to watch as he breaks down would-be defenders, like he did in Game 2 against the Flyers when eluding pressure on the half wall before sending the puck to the other side of the rink where Dennis Wideman  and Blake Wheeler  ended up assisting Miroslav Satan (who else?) on a goal.
Fact of the matter is, without Krejci, this magical playoff run the Bruins are on will probably come to and end. Center is the deepest position on the Bruins between Krejci, Patrice Bergeron , Marc Savard , Vladimir Sobotka and Steve Begin but Sobotka is not the type of guy who can step up his game to the point of coming anywhere near being able to replace Krejci. Sobotka is a high-effort guy, concerned enough with just keeping his spot on the roster, let alone turning in to an offense-first NHL  centerman.
So, sans Krejci, Boston just does not have another guy like that who can extend their roster. Savard, Bergeron and Krejci are supposed to complement each other, not replace each other. If Savard could have started ramping up his production coming off a Grade 2 concussion, you would have to like the Bruins chances against anybody in the NHL  with their skill down the middle. There are no forwards on the roster who, without some extraordinary breakout playoff hysterics, can pick up that production. If you look at the Bruins roster they are strong on defense (and about to get stronger if Mark Stuart  can come back soon), great in goal with Tuukka Rask  or even Tim Thomas  (because, yes, Thomas can still be a great goaltender) and deep down center. Forward is the lacking position and [potential No. 2 overall pick] Taylor Hall  would be quite a welcome addition to the team come training camp next fall.
But that does not help the Bruins right now. With or without Krejci, there is almost no way that the Flyers are going to beat Rask four straight to take the series, but the production and roster-lengthening effect of Krejci cannot be replaced. This is especially pertinent if the Bruins end up playing the Penguins  who are perhaps the deepest team at center in the entire league with Sidney Crosby , Evgeni Malkin and Jordan Staal.
Either way, it is a sad day for the wily Czech. Knowing his quiet intensity, it will be difficult for him to watch his teammates continue to battle for Lord Stanley’s Cup from the press box.
