Rob O’Gara is in a unique situation.

In a league where some players make their debuts as teenagers, the Boston Bruins’ 2011 draft pick spent four years at Yale University before playing in his first NHL game this season.

The defenseman, who played in three games before being sent to the American Hockey League’s Providence Bruins, is a prospect B’s fans definitely should keep an eye on this season.

Hear more about O’Gara from NESN’s Dale Arnold, Billy Jaffe and Barry Pederson in the “Big Bad Bruins Live” video above.
