Season 2 of “Behind the B” premiered Monday night on NESN, and the star of the episode was Boston Bruins first-round pick David Pastrnak.

The 18-year-old winger, who the B’s selected 25th overall, showed his colorful personality at the 2014 draft in Philadelphia and during the team’s development camp at Ristuccia Arena.

The episode also focuses on Dennis Seidenberg’s recovery from major knee surgery. The veteran defenseman has put in a lot of hard work off the ice to get his knee back to 100 percent strength.

Check out Pastrnak, Seidenberg and much more in the hour-long season premiere below.
