Strengths: Pro Bowl C Maurkice Pouncey and G David DeCastro form the nucleus of a strong interior and are part of a youth movement that will feature at least four starters under the age of 25.
Weakness: The inability to stay healthy and develop consistency has plagued the line. And there is uncertainty with Marcus Gilbert moving to left tackle.
Needs: An effective pulling left guard who can enhance team's ability to run its bread-and-butter counter plays. More depth at guard, especially if Ramon Foster is not re-signed.
Overview: The line will undergo a major overhaul with the departure of two, and maybe three, starters. But, with so many young players and an emphasis on athleticism, the unit has a chance to grow together and be more effective.Steelers
