CSNNE.comLOS ANGELESHere are five thoughts from the first period of Bruins and Kings at the Staples Center with the Bs trailing Los Angeles by a 1-0 score after 20 minutes of play.1)The Bruins left the Staples Center angry about several calls the last time the Bruins traveled here for a game, and its starting out that way again for the Black and Gold. The Kings were given two power plays in the first on a Zdeno Chara penalty and a questionable holding the stick call on Blake Wheeler at the end of the period. The Chara call led to LAs only goal.2)Three shots on goal for Michael Ryder, who was very active in the first period for Boston and looks to be having one of his good nights.3)A good scrap between Shawn Thornton and Kyle Clifford designed to wake the Bruins up a little bit at the end of a sleepy first period. Well see if theres a response in the second period after things were slow to get going in the first 20 minutes for Boston at the tail end of a deceptively long two-game road trip.4)Interesting to watch the Bruins struggle to clear the front of the net with Mark Stuart standing as a healthy scratch and Zdeno Chara in the penalty box. Ryan Smyth simply crashed the net with both body-bangers out of the lineup and potted home a rebound after fighting through Johnny Boychuk and Dennis Seidenberg to get there.5)The Bruins could be getting accustomed to their new lines in the first period, so well see what happens in the middle 20 minutes. Anze Kopitar gave Tyler Seguin a pretty hard body check in the opening minutes of the first period to set a bit of a tone, and the Bruins have yet to really answer.6) Celeb sighting at the Staples Center: Harvey the semi-crazed drill sgt. from VH1's Celebrity Fit Camp milling around outside the rink prior to the game tonight. Not a big one, but still notable.
