With the Boston Bruins facing the Pittsburgh Penguins in the Eastern Conference finals, one of the biggest storylines features Jaromir Jagr taking on the first team on his resume.

While some speculate what drives Jagr at this age to chase the Stanley Cup, there’s someone on the other side of the ice who knows. Brenden Morrow and Jagr played together this season in Dallas before each was traded to his current playoff team.

“He’s still just as excited as any 18-year-old in the locker room,” Morrow said. “His skills are still there. His big body’s tough to move when he’s planted and has possession of the puck. He played real well for us in Dallas, scored some big goals.

“He’s a threat every time he’s on the ice.”

The Penguins and Bruins open their series this week.
