If nothing else, the Pittsburgh Steelers have given themselves some options for the starting offensive line this season, at least along the interior. They signed two players in free agency who are very likely to be starters, and they can have a competition among retained players for that third spot, which is expected to be at left guard.
The incumbent there is Kevin Dotson, a third-year player who started nine games there last season before succumbing to a lingering ankle injury that kept him out for the rest of the season. His offseason trainer, Duke Manywheather, believes he can have a big here.
