Why don't hockey teams use extremely large men as goalies?

There are some very athletic huge men out there, think sumo wrestlers or linemen in American Football. So why don't teams use a gigantor to guard  the goal?

The rules limit how big a goalie's pads can be, so they don't show up with giant pads that block the goal.

So a fat guy might take up a lot of space, but much of his body will be unprotected from 150+ km/h slap shots.  He might block the first few, but he'll be leaving the ice on a stretcher before the game is over.
