By recording where a hockey puck goes into a net, a goalie can... 1. figure out which players are left handed
2. determine where they are not successfully blocking goals
3. analyze which shots were the fastest
4. analyze how much time needs to be spent in each part of the net

2. determine where they are not successfully blocking goals.

Explanation:

In the game of ice hockey, a goalie also referred to as goaltender refers to an individual (player) who is saddled with the responsibility of preventing the hockey puck from going into his or her net. When the hockey puck is prevented by the goalie, it simply means that the opposing team is prevented from having a goal or scoring.

The area in front of the net where a goalie plays is known as goal crease.

By recording where a hockey puck goes into a net, a goalie can determine where they are not successfully blocking goals because it helps them to see where they successfully made a save (block) and where they did not.
