Remember that 2017 playoff series against the Ottawa Senators, when the Bruins had to go deep, deep into their defensive depth chart?
Game 5 against the Senators featured the following defensemen: Zdeno Chara, a barely-out-of-college Charlie McAvoy, Joe Morrow, John-Michael Liles, Colin Miller and Kevan Miller.
Yup, that was the blue line during a playoff game. Remarkably, the Bruins actually won that game in double-overtime, but I digress.
That series proved the old sports cliche that you can never have too much defense.
