The Philadelphia Eagles had arguably the single most dominant offensive line in the NFL last season and it helped lead them to the Super Bowl. But unfortunately for the Eagles, they’re going to have to replace a key player on that offensive line this offseason.

After seven seasons with the Eagles, veteran guard Isaac Seumalo signed with the Pittsburgh Steelers this offseason. And Philadelphia center Jason Kelce doesn’t think Seumalo is replaceable.

“I think he’s one of the best guards in the NFL, and I think he has been,” Kelce told reporters Wednesday, according to NFL.com. “I think he’s one of the most consistent players I’ve ever been around, one of the most consistent people I’ve ever been around. So we’re not going to replace Isaac, there’s going to be someone new in there, and they’re going to have their attributes that they’re going to excel with, and I’m looking forward to seeing who does a really good job with that.”

Kelce went on to explain that he doesn’t think the average person understands how much Seumalo meant to the team and their offensive line.

“Isaac is a really, really special player,” Kelce said. “I know we’ve said that here for a long time, and I still don’t think people really truly grasp what he did for our room. And me personally, I think he’s probably the smartest player I’ve ever been around. Really, really gifted physically, mentally, across the board. So I think the Steelers are getting a steal, that’s a good pun, I guess.”

It will certainly be interesting to see how the team can perform without him next season.
