Zdeno Chara hopes his hard work off the ice keeps him on it

(Winslow Townson/USA TODAY Sports)

Zdeno Chara admitted on Tuesday that he wants to play beyond the 2017-18 season.

This isn’t news to Bruins fans. You’ve come to expect this from the 40-year-old captain, who has one year and $4 million remaining on his contract before he becomes an unrestricted free agent on July 1.

It’s been well documented that he has no plans on hanging up his skates any time soon.

He’ll also admit his best years (“nomination years” as he described it in regards to the Norris Trophy) are behind him, but he believes he can still be effective and help the Bruins win. He always believed he could play for a long time if he remained healthy and in good shape.

He’s healthy. No doubt he’s in shape.

So, how does he do it? And, how long will it last?
