Why don't they just get a 600lb fat mf'er and just sit him in front of the goal?
we have a volunteer
Because even a 1200#er wouldn't completely cover the goal and a goodly number of players can snipe a puck through openings you'd not think a puck might fit.
You could put 3-4 big, mobile, athletic Sumo guys with great stamina and flexibility all out in front of one goal in full pads and they're still gonna lose .
