The Boston Bruins and Brad Marchand couldn't agree on a new contract extension before ultimately trading him to the Florida Panthers.

The Brad Marchand Era in Boston has come to a close. The longtime Bruins forward was sent to the Panthers in a trade deadline stunner that officially signaled Boston’s commitment to a rebuild — and helps the Panthers replace Matthew Tkachuk.

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.

In a stunning move that no one saw coming, Boston Bruins captain Brad Marchand was traded to the Florida Panthers in a stunning move minutes before the 3 p.m. deadline on Friday.
