The most important factor when the puck is being carried behind the net is to maintain eye contact with the puck for the greatest amount of time that it is there.
Generally, goaltenders will stop watching the puck once it passes the post on the short side & begin to move in the direction the puck is being carried without bothering to maintain any type of eye contact with the puck until they arrive at the far post.
In other words, the goaltender is “guessing” that the puck carrier will continue moving the puck in a forward direction behind & around or beyond the net. And this really is a “guess”.
Simply, because, this does not consider the other 3 options at the puck carrier’s disposal:
1. the puck carrier can stop at some point behind the net & with a quick set up, make a pass out to a supporting partner on either side (result = panic: since goaltender is committed to one side of the net & has no idea where the puck carrier or puck is, he/she ends up turning his/her head from side to side in an attempt to determine where the attack will come from)
2. the puck carrier can make a back pass to a partner who is below the goal line & trailing the play (result = trailing partner steps out over the goal line & jams the puck into the open net near side or plays “catch” with the passer forcing the goaltender to bounce from post to post & completely out of position for any type of scoring attempt)
3. as he reaches the mid-way point behind the net, the puck carrier can make a back pass to a supporting partner who is already above the goal line on the same side of the net where the puck carrier started (result = easy tap in goal 9 times out of 10)
So, here is one method to "effectively" track puck movement behind the net.
The first point I want to make here is “don’t panic”! Remember, generally you will have more time than you realize especially, if you maintain excellent eye contact with the puck.
In this scenario we have chosen, the goaltender has positioned him/herself in an RVH (or for younger, less experienced goaltenders in an integrated post position on his/her skates) on the blocker side post as the puck is being moved below the goal line towards the net on the goaltender's blocker side.
The goaltender should hold this position on the post until the point where the puck has moved past the blocker side post inside the frame of the net. Now the goaltender moves his upper body away from the blocker side post but keeps his/her skate blade/pad in contact with that post and eye contact on the puck. At this point the goaltender will be positioned on the goal line & approximately MID-NET.
When the goaltender can no longer see the puck over his blocker side shoulder he should continue to HOLD THAT SAME MID-NET POSITION, turn his head & attempt to pick up the puck location over his trapper side shoulder.
If the puck carrier has continued his path forward with the puck, the goaltender should just simply use his/her trailing leg (the one still in contact with the blocker side post) to push off & engage and seal the trapper side post and the ice.
On the other hand, if the goaltender cannot locate the puck position over the trapper side shoulder, he should KEEP HIS POSITION & turn his head back to the blocker side & attempt to locate the puck on that side.
If the puck carrier has stopped & set up behind the net, the goaltender can still maintain eye contact on the puck simply by leaning a little more to one side or the other and reacting to what he does. Although, not totally integrated to either post, the goaltender's location still leaves him/her in a very, very favorable position to gain angle on a pass out to either side of the net or deal with a wrap around attempt.
If any type of back pass has been made the goaltender is still in a favorable position (MID-NET) to react to either of the back-pass situations described above because the goaltender is just a short push away from being able to quickly and effectively integrate with the post and seal the ice and/or gain angle against the scoring attempt.
We suggest this method is equally effective in situations where puck movement is similar but, where the goaltender chooses to remain on his/her skates and to not move into an RVH position.
(although we have used puck movement from blocker to trapper side of the net, the same method can be used for a puck being moved in the opposite direction)
