NFL Depth Charts
From Wikipedia, the free encyclopedia
An NFL Depth Chart is a contextually enhanced player roster published by each National Football League franchise.
The first column of players listed are part of the starting lineup. Each week in the NFL head coaches are required to submit a list of the players who will start the game in their designated position. Players who are regularly listed on the starting lineup for each game are considered starters. The second column of players are "back-ups" to their respective starters. Depending on the position, these players will rotate in with the starting players or will come into the game when their respective starting player is injured or performs poorly. The act of being removed from the game because of poor performance is called "benching" or being "benched". The third and fourth columns would be considered the back-up's back-up or the 3rd and 4th string of players. The 3rd string and 4th string designation refers to players that are 3rd or 4th in line for starting the game. Therefore, 2nd string would refer to the primary back-up and 1st string would refer to the starter. The 2nd, 3rd, and 4th string of players are usually given special roles in a game. These roles include special teams tackler, special teams blocker, kick returner, punt returner, third-down running back, H-back, goal-line back, slot receiver, and second Tight End in a two Tight End set.
In today's NFL, depth charts are updated year round because off-season player movement plays such a prominent role for fans and media alike. There are several opportunities during the regular and post season for updates as coaches update official weekly lists of starters for games. Head coaches also give verbal updates of player's starting or back-up roles in press conferences. During the off-season there are also several opportunities for updates to a depth chart. The post-season ends in February, free agency begins in March, the NFL Draft is in April, mini-camps are held in May and June, training camp opens in July, and pre-season games begin in August.
