With just four weeks to go until training camp, the Pittsburgh Steelers’ roster should be mostly complete at this point. There could be some other minor additions, but outside of a blockbuster trade for a wide receiver, it would probably just be adding veteran players who fail to make other teams’ rosters in late August when they are trimmed from 90 players to 53. Which of the Steelers’ position groups are top five on the team right now? This list will mostly be focused on the starting players, but depth is taken into account as well. We all learned how important that was last year at inside linebacker and safety in particular.
