Marchand pulls a Gronk when asked about Orr's 69th birthday

There's just something about Boston-based sports stars.

Bruins forward Brad Marchand channeled New England Patriots tight end Rob Gronkowski when asked about Bobby Orr on the legendary defenseman's 69th birthday.

"It's a great age," Marchand told reporters Monday, according to CSNNE's Joe Haggerty. "Great year. He's an incredible human being."

The comment came less than an hour after Marchand was named the NHL's first star of the week for piling up five goals and nine points in three games.

Gronkowski has shown a near-obsessive fascination with 'the sex number' over the years.

By all accounts, this is new territory for Marchand, but we eagerly await Orr's response.
