Brad Marchand’s hockey afterlife officially began Tuesday morning on Causeway Street, where he returned to the ice for the first time in more than a week, and for the first as an ex-Bruin.

Marchand wanted to play his entire career in Boston. His leadership and the team’s culture was something new Bruins always said they had admired from afar and made them want to be part of the organization. That doesn’t mean the Bruins should have caved to any demand Marchand made, but trading him will be noticed.

Aleksander Barkov looked across the Florida Panthers’ locker room on Saturday morning and noticed a new addition.
