In 2014, the Eagles' offensive line suffered through a severe lack of continuity, as the projected starting combination of Jason Peters, Evan Mathis, Jason Kelce, Todd Herremans and Lane Johnson never played a single snap together as a full unit. Here's a chart of what offensive linemen started each game last season:
| Opponent | LT | LG | C | RG | RT |
| Jaguars | Peters | Mathis | Kelce | Herremans | Barbre |
| Colts | Peters | Kelly | Kelce | Herremans | Gardner |
| Redskins | Peters | Kelly | Kelce | Herremans | Gardner |
| 49ers | Peters | Tobin | Molk | Kelly | Herremans |
| Rams | Peters | Molk | Herremans | Johnson | |
| Giants | Peters | Tobin | Molk | Herremans | Johnson |
| Cardinals | Peters | Tobin | Molk | Herremans | Johnson |
| Texans | Peters | Tobin | Kelce | Herremans | Johnson |
| Panthers | Peters | Mathis | Kelce | Tobin | Johnson |
| Packers | Peters | Mathis | Kelce | Tobin | Johnson |
| Titans | Peters | Mathis | Kelce | Gardner | Johnson |
| Cowboys | Peters | Mathis | Kelce | Gardner | Johnson |
| Seahawks | Peters | Mathis | Kelce | Gardner | Johnson |
| Cowboys | Peters | Mathis | Kelce | Johnson | |
| Redskins | Peters | Mathis | Kelce | Gardner | Johnson |
| Giants | Peters | Mathis | Kelce | Gardner | Johnson |
As a result, the Eagles went from gaining 160.4 rushing yards per game on 5.1 yards per carry in 2013 to 124.5 yards per game on 4.2 yards per carry in 2014.
Earlier this offseason, the Eagles released Todd Herremans, and rumors persist that the they will either trade or cut Mathis. Obviously, if the Eagles were to lose each of their starting guards in one offseason, there wouldn't being be a single player along the offensive line who will have had much experience playing to whoever is next to them.

Appearing at Herremans' 3rd annual Hoops for Help Fundraiser, starting center Jason Kelce spoke about the Eagles' offensive line continuity heading into the 2015 season.
"I don't know how (Mathis' situation) is going to unfold," said Kelce. "I think that a lot of the backups had significant time last year, so there's some cohesion there that has already been built up with some of the backup guys and myself already, and the tackles."
However, Kelce was also clear to note that replacing Mathis and Herremans may not be easy.
"I played next to Evan my entire career at left guard, and Todd for the majority of my career at right guard. They've helped me do my job. They've been great anchors for our line for a long time now, and any time you're replacing guys, there's going to be some much needed practice and much needed work to make sure that the guys coming in are getting the job done."
The Eagles saved $2.8 million off their 2015 cap by releasing Herremans. They'll save $4.5 million if they cut or trade Mathis. Will it be worth it?
