The Oakland Raiders went into the 2018 season with one of the better interior offensive lines, as they started Gabe Jackson and Kelechi Osemele at guard, and Pro Bowler Rodney Hudson at center. When we rank the top offensive lines in the NFL, we often rank them based on several different factors.
For example, If we want to see which offensive lines are the best at pass blocking, we typically look at the total sacks given as a unit. Now I totally agree, total sacks given up are super important.
However, coaches and scouts know to look at other advanced metrics other than total sacks.
