I'd have to disagree with the physics in that, while the puck does have kinetic energy it is directly proportional to the velocity. If the puck has to be shot at an angle perpendicular to the path of motion you must stop the momentum the puck has in that direction, and put it in a new direction with requires energy - so some of the energy that could go into shooting the puck in the new direction is taken away in order to stop it's current motion. So by the time the puck is shot, the kinetic energy it originally had is already gone.
And while the friction would take away from the shot, I would expect the second the puck is no longer in contact with stick it is off the ice, negating any frictional loss.
I really would think that in a hardest shot contest there is a clear advantage to getting the "hardest" shot based on the fact the skater is skating forward, has no interuption, and is purely trying to hammer the puck as hard as possible and nothing else.
But that's just my two cents.
