It was a play that would be frowned upon in youth hockey. And yet, there was the pass by Boston University’s Ben Rosen, the puck going far too close to an open goalmouth, the goalie in no position to do anything when Northeastern’s Kevin Roy intercepted the puck and poked it in.

Sure, Rosen was attempting a pass to teammate Sean Escobedo. But with the goal unoccupied it was risky at best, and calamitous at worst. And in looking at Rosen’s face once the puck had crossed the goal line, the BU player knew just how badly he had erred.
