  • 1. The Shrinking Net theory to Goaltending
  • 2. When a goalie plays on the crease line, the true dimensions of the net the goalie is protecting are 3’ high by 5’ wide. 4’ X 6’ 3’ X 5’
  • 3. Who said you don’t need geometry to play hockey?
    • When 4 ropes are attached to the 4 corners of the net and pulled to an apex, a pyramid is formed.
    • As a goalie moves away from the base of the pyramid, (formed by the goal line) a smaller pyramid base is formed.
  • 4. Tell your goalies to fill the pyramid
    • If a player shoots a puck that goes outside the ropes when the goalie is at the top of the crease, then the puck will miss the net on the goal line.
  • 5. A tool to show how to play in the proper position
    • The smaller goal frame placed at the top of the crease touches the 4 ropes, marking the amount of net a goalie has to protect.
    • The dimensions of the ropes when measured at the top of the crease is 3’ X 5’
  • 6. From the shooters eye This shows the part of the net that a shooter sees. Note how much net appears to be open above the Crossbar of the goal frame placed at the crease line.
  • 7. A view from the eye of the puck But from where the puck is coming from, there is no visible net outside the perimeter of the plastic goal frame when placed on the crease line.
  • 8. A goalie filling the “True” goal. Still looks like a lot of net open up high.
  • 9. So, why play the butterfly style?
  • 10. Because a goalie can still cover the high part of the net, while maximizing coverage down low. Remember, a puck shot above the crossbar of the plastic goal frame at the top of the crease will go over the net on the goal line.
  • 11. When the goalie is square to the puck and centered in the opening, this style maximizes coverage.
  • 12. When the angle changes, the dimensions of the “True” goal shrink even more. 3’ X 4’ Rope are aligned with a puck on the boards at the blue line.
  • 13. From the view of the puck. Notice the position of the hands.
  • 14. Butterfly position to maximize coverage, but beware.
  • 15. There is actually more net open up high on the short side. Rope touches plastic goal frame on far side, but not the short side.
  • 16. A view from the other side showing more net up high on the short side.
  • 17. Shot aligned with in-zone face-off dots. 3’ X 3’
  • 18. A view from the puck’s perspective. More net up high No net showing
  • 19. Maximum coverage of the “True” goal.
  • 20. Goalies must be square to the puck and centered in the “True” goal. Goalie is not centered, which leaves open net.
  • 21. Puck view of goalie not centered.
  • 22. Net aligned with a puck at the bottom of the face-off circles. 3’ X 2’
  • 23. Puck view from same angle.
  • 24. The goalie can cover the area in an upright position.
  • 25. Why butterfly from this angle?
  • 26. It helps the goalie with rebound control. It drops the hands into position to catch low pucks.
  • 27. Goalie drills to do with your players
