You are partly right about that, Jeff. I consider the Saints’, the Rams’ and the Chargers’ offensive lines the best in the league right now, with the Rams’ a little in front of the two others.
The Rams were the only team last year that had the same combination of five players for 15 games after they stroke gold with left tackle Andrew Whitworth and center John Sullivan in free agency before last season. This season right guard Austin Blythe is the only new starter, while Aaron Kromer has been their offensive line coach in both 2017 and 2018, and now he is also their run game coordinator which means that he has even more control of what Todd Gurley needs and gets.
The Saints return all five starters from last season, though they didn’t play together last season for more than 10 games, and still they were easily the best offensive line in the league. They don’t even knew each other that well since right tackle Ryan Ramczyk was drafted in the 2017 draft, and right guard Larry Warford was signed in free agency 2017. I think that’s a tribute to offensive line coach Dan Roushar, offensive coordinator Pete Carmichael and head coach Sean Payton.
The Chargers’ offensive line has four starters that played together last season, while they have been inserting a new center this year. The line was good last season but have been fantastic so far this season. Last season they inserted three new starters, two of them during the season, so they haven’t been playing together for that long. This is only the offensive line coach, Pat Meyer’s, second season, but since the unit has four new starters since he was hired, a lot of the credit for their success has to go to him for his input and coaching. Also, their head coach, Anthony Lynn, has long had a focus on the offensive line as he was a runningback himself and later on has been a runningback coach for many years.
I think an interesting side note is that all three of those teams have both good quarterbacks and runningbacks what definitely makes an offensive line better.
I went through how the Cardinals have prioritized the unit since Keim was made general manager. You can read it by clicking

I also think Ray Brown is a good offensive line coach, but it takes time to form a good unit.
