A perfect helmet angle is crucial for players and coaches to focus on the football, avoid getting hit and make their jobs easier.

A study published this week in the journal Science found that a player’s head angle affects his or her ability to see through fog, create and maintain a clean line and reduce the amount of debris in the field.

Researchers compared helmet angles for 32 NFL players who played in the NFL’s 2011 and 2014 seasons.

They found that the players who saw their helmets angled higher than the average angle of their head at the time had the lowest performance on three specific performance measures: accuracy, focus and visual acuity.

While most NFL players are familiar with how a helmet angle affects performance, the researchers also looked at how this angle affects their ability to focus.

They analyzed data from 634 players from both the 2011 and the 2014 seasons to examine how their head angle affected their ability and accuracy in a task that involves using visual cues to predict the direction of an incoming ball.

Researchers then used an algorithm to determine the best angle of head for a given player.

The optimal angle is determined by how far a player is from the center of their helmet, as measured in the center-of-the-board (CTOB) measurement, or the point where the eye is closest to the center line of the helmet.

The researchers then measured the angle of the head from this angle to determine a player ‘s head angle.

Players with a higher angle of vision were better able to predict where the ball was going and avoid getting knocked out of position, according to the study.

This is due to the angle being further away from the face.

A different angle is required to use a different cue to predict how fast the ball will go by the defender.

Researchers found that players with a high angle of sight were more accurate in predicting how fast a player was going, according the study, which was published in the Journal of Sports Sciences.

The findings are based on two separate studies, which were done by the same group.

The first study examined the impact of a player and helmet angle on their accuracy and focus, while the second looked at the effects of different head angles on their ability at predicting where the game will go.

The study included both players and players who were blind to the fact that they were blind.

Researchers looked at players’ performance at three performance measures — accuracy, accuracy with visual cues and visual attention — to determine how the angle affects the players’ ability to use visual cues.

Players who saw the head angle higher than average at the start of the season had a higher accuracy rating at all performance measures.

This increased accuracy was greatest for the players with higher angles of vision.

The researchers also found that higher head angles were associated with better performance at multiple performance measures, including the following: accuracy and visual speed, focus, visual acency, speed of visual perception, vision at different distances, visual focus, distance vision and focus.

These findings suggest that a helmet’s angle is a key to maintaining a clean and consistent look and feel, according a statement from the study authors.

In general, players with better head angles are better at using visual tools to determine where a ball will be, the authors said.

However, the study’s findings are not a silver bullet for players, the scientists said.

The study is limited by the fact the study was limited to one single season and that the results may not apply to a wide range of players.
