agh...in this day and age of goaltending, there is not a defined "style" of goaltending.
even a "standup" goalie will drop down to the butterfly to make some saves, and a "butterfly" goalie will play certain shots on their feet. if you have to label modern goaltending with a "style" i would say that most goalies nowadays use a "pro-fly" or "hybrid" style of play. there are certain save selections that are good for certain types of shots, and saying that someone is a stand-up goalie or a butterfly goalie is meaningless, because nobody will use just one technique on ALL types of shots.
goaltending styles do not and should not dictate the way a goalie plays a shot - rather the shot should dictate the approach a goalie takes to make the save or play.
