A native of Belleville, Ontario, Shaw is known for his blue-collar approach to the game.

His performance in the 2011 Memorial Cup with Owen Sound of the Ontario Hockey League got him noticed by Chicago Blackhawks scouts. His numbers -- two goals and seven points in four games -- were eye-catching, but it was his style of play, toughness and willingness to do the dirty work that were the real hook.

The Blackhawks selected Shaw in the fifth round (No. 139) of the 2011 NHL Draft. He split his first pro season between Rockford of the American Hockey League and Chicago. Upon his call-up, Shaw's pugnaciousness was an immediate smash in Chicago.

In 2013, he played all 23 playoff games as Chicago won the Stanley Cup. In Game 1 of the Stanley Cup Final against the Boston Bruins, Shaw scored on a deflection off his leg at 12:08 of the third overtime to give the Blackhawks a 4-3 victory.

Two years later, Shaw again played in all 23 playoff games to help the Blackhawks win another title.

Chicago coach Joel Quenneville called Shaw "irreplaceable," but the Blackhawks, facing salary-cap issues, traded the restricted free agent to the Montreal Canadiens on June 24, 2016. Three days later, the Canadiens signed him to a six-year contract.

After three seasons in Montreal, Shaw was traded back to Chicago on June 30, 2019.
