0 out of 32Joshua Bessex/Associated PressLet the games begin. These are preseason games.Some NFL teams simply want to make it to the regular season. Other teams have a lot to decide on in the next weeks. On-field action will also play a part in deciding which direction they go.Each team's view can quickly change. Already at the start of training camps, differences can be clearly seen. Injuries and competition are part of NFL life. Both are part of daily life and can often decide whether a team will be successful in the regular season.Although depth can be developed through camp sessions it is not possible to build it during the preseason. Teams with the most talented rosters, from top to bottom, are the ones that will be standing when the postseason begins. The quality of each roster's depth at the moment is a projection. This will change in the coming weeks.This preseason is significantly different than previous ones. The exhibitions will be limited to three teams (except the Dallas Cowboys, Pittsburgh Steelers and the Steelers who had four after the Hall of Fame Game). The regular season will start once the rosters have been culled.Bleacher Report's team made an inventory of the league's hierarchy. Composite scores were used to determine the site's power rankings before the start of preseason.
