Takeaways: Bruins face mix of questionable calls and self-infliction in Game 5 loss

There’s no sugarcoating the Bruins’ Game 4 loss.

Without Brad Marchand, Jim Montgomery’s club came out with a productive physical and emotional response on the heels of Sam Bennett’s sucker punch to the Boston captain early in Game 3.

Charlie McAvoy’s thunderous open ice hit on Sam Reinhart on the opening shift brought a spirited TD Garden crowd to its feet.

The Bruins rode the energy from the Causeway faithful and carried a 2-0 lead into the first intermission off a David Pastrnak power-play blast and a Brandon Carlo seeing-eye shot through traffic.
