David DeCastro and Mike Adams will start for the Steelers at offensive line in their first preseason game of 2012. DeCastro was the 24th overall pick in the 2012 Draft, while Adams was selected in the second round. DeCastro is starting at right guard as Ramon Foster slides to left guard for the injured Willie Colon. Adams has already moved ahead of Trai Essex on the depth chart, but it is unclear if he or Max Starks will begin the regular season at left tackle. "There have been no signs of panic or anything like that," said offensive coordinator Todd Haley. "They have a long way to go, but, to this point, they've kept their cool and they look, physically, like there's no overmatched situation. This will be a great test for them. We'll know a lot more after the game where they stack up."
