The 40-year-old Zdeno Chara, less than a month away from turning 41, is turning back the clock for the borderline unbeatable Bruins. And it’s honestly been nothing short of absurd. His latest throwback performance? Oh, you know, just your casual complete shutdown of the game’s reigning MVP and most dynamic, unstoppable offensive player. In Tuesday’s 3-2 comeback win over the Oilers, Bruce Cassidy found a way to match the 6-foot-9 Chara on Oilers captain Connor McDavid for all but one minute and nine seconds of McDavid’s 16:23 of five-on-five time on ice. And it was in that 15:12 head-to-head segment that Chara and the Bruins dominated in the possession game, with a 62.5 Corsi-For percentage against McDavid, and with the B’s out-chancing the Oilers 12-to-4. (This came with nine of McDavid’s 20 zone starts beginning in the Boston zone, no less.) Most importantly, though, the Bruins outscored the Oilers 1-0 in this span. The goal, by the way, was the David Krejci game-winner scored with 1:04 left in the third period. McDavid’s final line read zero goals, zero assists, two shots, and a minus-1 rating, making it just the 10th home game this season in which McDavid was held without a point. Both of his shots came in a two-second span by throwing a pair of backhanders on goal from in tight. It was the lone moment that McDavid found anything close to separation from Chara. But Chara has made a habit of swallowing elite offensive talents like it’s 2008 all over again, even when away from the beloved last change benefits at TD Garden.
