For most teams in most NFL seasons, the offensive linemen are not superstars.

Their work of attempting to prevent men of around 300 pounds from breaking into the backfield and trying to create lanes for the ground attack is a remarkably difficult one, but it is not normally one that is conducive to receiving large amounts of attention.

It may, therefore, seem a little bemusing on first blush to see center Jason Kelce with a plethora of cameras pointed in his face ahead of Super Bowl LVII.

Kelce is, of course, playing in special circumstances as he and Kansas City Chiefs tight end Travis Kelce prepare to become the first brothers to go against each other in a Super Bowl.

But the attention is not limited to Kelce. Tackles Lane Johnson and Jordan Mailata each gathered a crowd this week at the Eagles' media availability and, as the former heavily emphasised ahead of their clash with the Chiefs on Sunday, being out of the ordinary is a defining trait of this group.

The makeup of the Eagles' offensive line is marked by its level of contrasts. Kelce and Johnson stand as the veteran lynchpins, two perennial All-Pros who have long since set the standard at their respective positions and are destined for the Hall of Fame.

On the other side of the spectrum, there is left tackle Mailata, the Australian former South Sydney Rabbitohs rugby league player who was selected in the seventh round of the 2018 draft having never played a single down of American football but blossomed so quickly that he is now the Eagles' undisputed starter at one of the most critical positions on the roster and represents the biggest success story of the NFL's International Player Pathway program.

The stark difference in the journeys of the players anchoring the middle and the right side of the O-Line from that of the unexpected star on the left side is a situation unique to the Eagles. 

But the Eagles have thrived on being unique in 2022. Their multi-faceted offense is unique in how it slows even the strongest and fastest defenses through the way in which Philadelphia utilise their dual-threat quarterback, Jalen Hurts, who has experienced a leap few envisaged in 2022.

And the joy they have experienced on offense has come in large part because the mix of All-Pro veterans, two extremely dependable guards in Landon Dickerson and Isaac Seumalo, and a left tackle who has gone from greenhorn to a foundational piece of the attack has produced a calibre of play up front that no team in the NFL can match.

Indeed, the Eagles rank first in Stats Perform's pass block win rate and second in run block win rate, dominance that can be attributed to the approach of offensive line coach Jeff Stoutland, whose distinctive coaching style helps make sure his group are never ill-prepared for any eventuality they might face on gameday.

"He's unique, he makes every meeting like a gameday with his voice," Johnson said of Stoutland.

"He's very loud, he asks a lot of questions, we call those 'cold calling' questions, which is like a pop quiz, a lot of that puts you on the spot, answer questions under duress. 

"He likes to simulate a game-like meeting room, which can be uncomfortable at times but you kind of respect it and you love it."

The numbers illustrate the merits of Stoutland's unconventional brand of coaching.

Johnson ranks second in pass block win rate (89.6 per cent) among offensive linemen with at least 100 total plays, Dickerson is ninth on that same list with a win rate of 83.5 per cent.

Dickerson's pressure rate allowed of 3.9 per cent is the best among all guards, while Kelce (2.0) and Johnson (2.9) rank second in that regard among centers and tackles respectively. 

Seumalo's 7.0 per cent may be less impressive, but it is still average (7.1) for guards this season.

Both Seumalo and Dickerson have unquestionably benefited hugely from playing next to Kelce, whose aggregate win rate across pass protection and run blocking of 83.48 per cent is the second-best in the NFL behind only Laremy Tunsil of the Houston Texans.

In the mind of Seumalo, who is finally solidified as a starter and was named a Pro Bowl alternate following years of persistent injury troubles, both Kelce and Stoutland deserve tremendous credit for how the Eagles' offensive line has coalesced into the elite unit in the NFL.

"To be a good offensive line you need really good players, and then Jeff Stoutland continually puts us in positions to be successful, we stick to our bread and butter and don't try to do too much," Seumalo told Stats Perform. 

"And then on the field Jason Kelce puts us in really good spots. When you have a combination of really good players, really smart players and an offensive line coach that continually puts us in good positions, it’s going to be successful. 

"Jeff Stoutland's work ethic is unmatched in terms of scheming and then knowing how to get guys lined up a certain way and also being ready for a lot of the grey.

"Being like 'let's show them what we expect' and then again, you're always going to get what you didn't see and then being ready to see that kind of stuff too. 

"Sometimes it's going to be tougher than what it should be, the easier and simpler you can make it the better."

Mailata's progress encapsulates Stoutland's ability to make things easy on his players. While he is still far from the finished article in pass protection, giving up a pressure rate of 11 per cent, he has excelled at preventing teams from disrupting the Eagles' ultra-versatile run game.

He has allowed a run disruption rate of 6.6 per cent that is ninth among all offensive tackles to have played at least 200 snaps in 2022, conceding a disruption to a defensive player on only 27 of his 411 run-blocking snaps.

Johnson believes there is much more to come from Mailata and Dickerson, who entered the NFL with the equivalent of a football masters degree having played at Alabama under Nick Saban but has still demonstrated surprisingly quick progress in making the switch from center to guard after suffering a knee ligament injury in his final season with the Crimson Tide.

"You look at it just the size they have with Mailata, Landon, the strength they have is unique," added Johnson.

"There's a lot of boxes they’re checking, which is physically gifted, speed, the more they're playing the better they're getting, they're on their way to be consistent top of the game every year."

Mailata and Dickerson checking those boxes has allowed Hurts and the Eagles' skill position-players to torment opponents who reside in the defensive box, with linebackers consistently crippled by hesitation due to the variety of threats they must account for when reading the Eagles' quarterback at the mesh point with his running back.

Hurts would of course not be able to generate such indecision in the minds of defenders without faith in the ability of his offensive line to hold up.

However, with aggressive defensive lines who get too far upfield in their efforts to pressure Philadelphia's quarterback extremely susceptible to the run, the line's odds of keeping the pass rush at bay are improved by facing defenders who are fighting their natural instincts, with that internal conflict also enabling the Eagles to get their blockers on the front foot in the run game and create chasms for Hurts, Miles Sanders and Kenneth Gainwell to surge through.

"The threat of Jalen, he's become a really good passer this year, his ability to run and get a lot of offense there helps our offense tremendously and then his ability to scramble and make plays for sure is helpful, helps everybody, it’s definitely an advantage," added Seumalo.

In his praise of Hurts, Johnson once again leaned on what appears to be his favourite descriptor of this Eagles' attack.

"Just a unique guy with his strengths," said Johnson. "His ability to run, he's dynamic, so [with the] gameplan, you have to be very crafty with what you do because when the play breaks down he can scramble for 30 yards. Unique player."

Johnson clearly believes Philadelphia's offense, particularly the line, is one of one. Should the Eagles keep a Chiefs defense led by All-Pro defensive tackle Chris Jones at bay and prevail in Glendale, then there won't be many doubting Stoutland's group deserves recognition as one of the standout offensive lines of the Super Bowl era.
