Now in his 21st NHL season - and 13th with the Bruins - Chara has had to adapt to an ever-changing league, that now puts a premium on skill and speed, rather than size and physicality.
"You have to make those adjustments," said Chara, who confirmed that he needed a couple of stitches following Game 1 to close a cut after blocking a shot in the final minutes. "You've got to be a little bit ahead of the game, as far as seeing what's happening with players coming in, how skilled they are, how fast they are, systems the way the teams are being coached. If you're not, then you're gonna be way behind.
"Kind of sensed where the game was going the last few years and tried to work really hard in the offseason, during the season. The ability to read plays better, not being caught in the wrong position on the wrong side of the puck, but try to obviously use my size still to my advantage.
"If you continue to work on your game and work hard to be better, you can play for a long time."
While still the team's No. 1 defenseman, Bruins coach Bruce Cassidy has worked with Chara to put him in the best situations to succeed, which has included cutting down a bit on his minutes. Nevertheless, Chara's will remains unmatched.
"Obviously his fitness level, his commitment to staying young even though he's older," said Cassidy. "That's his eating habits, his preparation. And then you take that away and he's a very intelligent guy…he's adapted some of his skating style, how he has to manage the puck. Guys are quicker, they can get under him. He has to move it differently. That's probably it. And then you have the competition factor, you can't measure a guy's will."
