I have to politely disagree, Sven. If we look at your diagram and the goalie takes the left hand side option he will immediately create a shepard situation by placing his colleague's body in such a place as to obstruct the attacking opposition player from access to the puck and the ability to attempt a tackle.

It would be a grey area if the Goalie chose to swim left but at an angle parallel to the goal tray (i.e. 90 degs to where he is facing now). Taking the puck back into 'the ****' as you drew it felt funny to me. As a player I instinctively wouldn't take either of the options suggested in your diagram . I would probably swim 90 degrees or less to the right side. This would keep me out of the horde of advancing players (that should be coming with the attacking forward) and also allow me to keep my body between the attacking horde and the puck (I'm a rightie- Nicky might take the opposite option because he's a lefty).

As a ref I would call a left sided dummy in the way you drew it a shepherd if the attacking player made any effort to retrieve the puck and was impeded by the retreating defensive player. Intentionally or not the Goalie will have created a shepherd and it sounds like at least Nicky and Tuck agree.
