There probably isn’t a team in the NFL that doesn’t have some level of competition for starting jobs in their training camp this year. it’s almost impossible to return 25 starters, including special teams, from one year to the next, for a variety of reasons. The Pittsburgh Steelers are no different, even if they are one of the more stable franchises.
With the retirement of Ramon Foster, the biggest question is how to reconfigure the offensive line. They could plug in free agent signing Stefen Wisniewski at left guard, where Foster played. Or they are looking into moving starting right tackle Matt Feiler inside, with an eye toward one of their young tackles moving into the starting lineup.
