Training camp for the Atlanta Falcons kicks off on July 24, and while the offense appears stable, several defensive positions are up for grabs. The most intriguing battles involve new faces, including rookies, vying for starting roles. Key matchups to watch include safety positions, where Jordan Fuller, signed to fill the void left by Justin Simmons, competes against rookie Xavier Watts. Also, at linebacker, Troy Andersen's performance will be critical to determining the team's defensive strategy. A strong showing in these battles could dramatically affect the Falcons' defensive outlook heading into the season.
