The Philadelphia Eagles have many questions to answer regarding their roster, but the offensive line isn't really one of them.

Each starter across the offensive line is signed and could be back next season, including left tackle Jason Peters, who will turn 35 later this month.

However, one of the biggest unknowns facing the team is what will happen at the left guard and center position.

In Allen Barbre and Isaac Seumalo, the Eagles have two players who have the capability of earning a starting spot on the offensive line.

Barbre has started and played all over the Eagles line since signing a free agent contract with the team before the 2013 season. A veteran of nine NFL seasons, he has been very solid at both left guard and right tackle.

But when injuries forced Barbere to swing out to right tackle and Brandon Brooks missed time with with an anxiety issues, it created some uncertainty on the offensive line. Rookie Isaac Seumalo got the nod for the two games in Brook’s absence, he started one game at left guard and another at right tackle.

The third-round pick played well, but now the question is, where does he fit in next season?

Seumalo played some center while at Oregon State, and many draft experts believed that might be his best NFL position. However, Eagles Vice President of player personnel Howie Roseman didn't seen ready to write an obituary for incumbent Jason Kelce just yet.

“He's been a consistent player since he's been in Philadelphia. [He has] exceptional athleticism. [He] played really well towards the end of the year and a guy that's been a true Eagle.”

The Eagles have some time to figure this out.

With Barbre about to turn 33-years-old and Stefen Wisniewski likely to leave via free agency, one possibility is Barbre becoming the swing player with Seumalo in the starting role.

Another second possibility would be Seumalo taking over the center spot and the Eagles cutting ties with Kelce.

Something to keep in mind, the Eagles could release either Barbre ($1.8M) or Kelce ($3.8M) if they like Seumalo and use that money to help some pieces elsewhere.
