Through four games, the Eagles’ offensive line, which was supposed to be a strength of the team, has fallen well short of expectations.

It might be time to think about making a switch … and it appears the Eagles are thinking about it too.

More specifically, the Eagles might be close to replacing left guard Stefen Wisniewski, who hasn’t played well thus far. The obvious replacement would be former third-round pick Isaac Seumalo, who began last season as the starting left guard before getting benched.

League sources indicated that Seumalo has been getting at least some first-team reps this week in practice, so there’s a good chance the Eagles have already seriously contemplated a move.

Even in the portion of practice open to reporters on Wednesday and Thursday, Seumalo took first-team reps at left guard next to Jason Peters and Jason Kelce.

This summer, offensive line coach Jeff Stoutland gushed about Seumalo, whom he said was having an “unbelievable” training camp. The one negative about Seumalo’s summer was that he had trouble snapping the football, something he won’t have to worry about at left guard.

And Seumalo is still just 24 years old. His teammates have said he’s much bigger and stronger this season, which might help him at guard. If the Eagles think they can finally tap into the talent that made him an appealing draft pick a few years ago, they should think about it.

Seumalo began last season as the starter at left guard but was benched after just two games. Initially, Chance Warmack took over, but then Wisniewski won the job.

"Wiz" became the starter in Week 4 and helped solidify the line as the Eagles went to the Super Bowl and brought the Lombardi Trophy to Philly. But through four games this season, Wisniewksi hasn’t been playing the same level as last year and didn’t have a good game against Jurrell Casey when the Eagles played the Titans on Sunday.

As a whole, the offensive line hasn’t been as good this year, but the left guard spot has probably been the weakest.

Seumalo was a third-round pick out of Oregon State in 2016. His versatility has proved helpful to the Eagles; Seumalo can play all five positions on the line.

Through four games, he’s played just 13 snaps, mostly as an extra blocking tight end.

Last season, Seumalo was handed the starting left guard job out of training camp without a competition, but he was so bad after two games, the Eagles made a switch. That’s why it might be scary if they go back to him, but it might be time soon.
