If the modern-NFL has taught us anything over the last decade-or-so, it’s that the best-of-the-best teams almost always have elite offensive lines. The 2011-2012 San Francisco 49ers offensive line was loaded between starters like Joe Staley and Mike Iupati. The Dallas Cowboys have three future Hall of Famers in Tyron Smith, Travis Frederick, and Zach Martin. The 2016 season saw the Oakland Raiders win 12 games and look like competitors, and a lot of that had to do with the play of Donald Penn, Kelechi Osemele, and Rodney Hudson.
I could go on with more examples, but you get the idea.
