If Shamarko Thomas ever wants to start filling Troy Polamalu's shoes, he's going to have to improve his mental approach to the game.
Thomas, who was expected to start at safety alongside Mike Mitchell, saw just four defensive snaps in Thursday's season-opening loss to New England. Will Allen will continue to play ahead of Thomas because of his veteran presence.
"He's got to be good above the neck," Tomlin said of Thomas via PennLive.com. "He's got to be in position to make plays, he's got to do a good job of communicating, some of the things that we thought Will Allen gave us a better opportunity to do well given the course of his experience."
