The defense in ice hockey used to be assessed in a rather crude manner. The players who blocked pucks, threw big hits, swept the crease clean, and looked intimidating were considered to be good defenders.
Of course, all that matters too, but it is not the end of the story. The defense in today’s NHL is much faster, more intelligent, and more complicated than the one from the old days. A good defender is not always a guy who delivers an ear-splitting hit. Sometimes the best defender is the one who prevents the action that would otherwise have been seen by the spectators.
This is how the NHL’s player tracking data makes the discourse on defense more sophisticated. One could stop at asking, “Did they block the shot?”, but thanks to the new technologies, one may go further and ask, “How did the shot come about?”
Defense Has Become More Than Just Slap Shots And Blocks
For quite some time, the performance of a defensive player was assessed through certain statistics. Coaches and spectators used numbers such as hits, blocked shots, plus-minus, penalty killing, and goals against. The numbers provided the necessary information, but were sometimes deceiving.
A player with a great number of blocked shots may be courageous. However, they might be wasting their time being stuck in the defensive zone. The other player may seem passive because of having fewer hits, but actually uses positioning to prevent attacks.
The students specializing in the field of sports analytics, coaching, or data writing will benefit greatly from this transformation. Whenever deadlines start mounting for the learners, some of them use services such as write my essay to get more time to watch game video, compare data from the NHL and comprehend modern defense systems. Analysis requires concentration and is sometimes effective when done slowly.
According to Adam Jason, who is an expert on sports education and analytics, the use of data makes one able to see the work of defense that was invisible before. This is a key thing to remember. Not all effective plays end up in a hit or a block. Some defensive plays result in the opposition being unable to take any shots.
Additional Information Provided by NHL Tracking Data
The data obtained using NHL tracking provides additional information on how the players and puck behave during the match. As can be seen on the official NHL EDGE platform, it uses both puck and player tracking data, and it shows statistics regarding skating speed, skating distance, shot speed, shot location, and zone time. In this regard, it is worth taking into account the NHL EDGE official explanation for a better understanding of how the new statistics give fans access to data that was impossible to obtain earlier.
As far as defense is concerned, it should be noted that hockey is a game of space. Effective players know how to control space before it becomes dangerous.
This tracking data reveals the elements that make up these hidden aspects of the game.
Gap Control Becomes More Transparent
Gap control relates to the distance between the defender and the attacking player. The bigger the gap, the more room there will be for the player to pass or skate past the defender or even shoot. Conversely, if the gap is too small at an inappropriate time, the defender will be cut wide by the attacker.
Excellent defenders know how to navigate this distance properly. These defenders are not always trying to track the puck; they are looking for things like speed, body angle, teammate coverage, and dangerous ice.
This type of data makes it easier to analyze because of the ability to see both movement and speed. When defenders control the gap tightly enough to make the attacker dump the puck out or take a bad-angle shot, this is a huge defensive win.
It is possible to apply this principle rather easily by recognizing not only the player who blocked the shot, but also the player who forced an attacker into taking a poor shot.
Zone Time Identifies Defenders Who Are Actually Playing Defense
Zone time is one of the most powerful concepts of modern defense evaluation. If a defender’s team has lower defensive zone time with them on the ice, then that means something.
Defense is more than just surviving attacks. Defense is putting out the fire.
If a defender wins puck battles, makes accurate outlet passes and helps the team on breakout play, that can decrease defensive zone time. And this results in fewer tired shifts, fewer desperate clearing attempts and fewer opportunities against.
That is how modern analytics revolutionizes the perception of defenders. The value of a stay-at-home defenseman is recognized, but the current game values defenders who are able to clear the puck, too.
Entry Stopping Is Key for Modern Defenders
One of the most significant evolutions in terms of defensive tactics includes the way teams approach zone entry. Traditionally, many defenders would back-check and allow the attacking side to enter the zone, defending once they got into the zone.
Currently, stopping a clean entry is more important than ever. The faster and more controlled the entry is, the greater the danger to the team. A forced dump-in and a breakdown of play at the blue line reduce the danger significantly.
Such stats will help in this aspect as they will allow teams to understand where players enter, how fast, and how defenders react to such entry.
An effective defenseman might:
- keep the blue line while avoiding overextension;
- direct the puck-carrier into the boards;
- make their opponent dump the puck rather than make an entry;
- stick within a reasonable range to apply pressure but not to be out-skated;
- recover quickly when the play switches directions.
These traits do not have a flair for the dramatic, but they can win games.
Defense Is a Five-Man Job
Moreover, tracking data confirms the fact that was already known to coaches long ago – defense is not the responsibility of only defensemen. Forwards play an important role too.
When a winger fails to perform an assignment, they may allow an entry point to remain open. If the center does not play low in the zone, the team will be outnumbered by its opponents. Slow change in positions of forwards can lead to an odd-man rush.
It is important in modern defensive schemes to involve all five players. It is easier to analyze how players work because of tracking data.
Team defense includes the following:
- The first forward presses the puck.
- The second forward blocks the second option.
- The third forward blocks the middle.
- The defensemen maintain gaps.
- All the players know when to press and when to protect.
It is easy to list, but difficult to achieve!
