The Steelers travel across the state to take on the defending Super Bowl Champion Eagles in their preseason opener on Thursday night. Like last year, many of the Steelers big-name starters will not dress for the game, so this will mostly be a showcase of the backups. Nevertheless, this will be the first major test for many players as they fight for their positions on the roster. The Steelers released their initial depth chart over the weekend, but it does not mean much as the first chart of the year typically organizes players based on length of tenure with the team.
