NFL training camps are entering an important stage as teams prepare for the first major preseason games.
With preseason action approaching, coaches across the league are evaluating players competing for starting roles, roster positions and depth-chart places.
Training camp is where many roster battles begin to become clearer.
Young players are trying to prove they belong, veterans are attempting to maintain their positions and coaches are looking for combinations that can work during the regular season.
Injuries also become important
The preseason period can be frustrating for teams because injuries can quickly change plans.
A player who misses several weeks may lose valuable preparation time.
Teams therefore need to balance competition with player health.
The regular season is approaching
Every practice and preseason game now carries more significance.
The coming weeks will determine which players make final rosters and which teams have solved their biggest weaknesses.
For NFL fans, training camp is where the first real clues about the new season begin to appear.
