One of the bigger surprises of the Flyers’ offseason took place on the first night of the NHL Draft, when Ron Hextall used the team’s second pick to go a bit off the board and take center Jay O’Brien. The pick may have caught the casual viewer a bit off-guard, for one particular reason: while many of the players taken in the first round spent their draft years playing in one of the well-known Canadian junior hockey leagues, or perhaps against professionals in Europe, O’Brien spent almost all of his draft season squaring off against American high school players with Massachusetts’ Thayer Academy.
