Pro Football Focus Offensive Line Delta Rankings

Jul 5, 2017

By: @DFS_mathlete

Pro Football Focus (@PFF) regularly releases articles on team offensive line ranks. I created a table comparing how the ranks have changed from the end of 2016 to the start of the 2017 training camp.

People debate exactly how useful an offense line rank is for fantasy. I won’t be drawing any conclusions on how these rankings relate to specific players because I don’t have any data to back it up. In general we know QBs play better with a clean pocket and running backs excel when they have good blocking.

On June 27, 2017 they released this article that ranked all the offensive lines heading into the 2017 season.

On January 11, 2017 they released this article that ranked all the offensive lines at the end of the 2016 season.

I compared the rankings between those two articles and came up with the table below. This shows how an offensive line changed through the off-season and where they are positioned going into training camp. I highly recommend checking out the articles. They help describe some unusual and unexpected changes such as the large NE fall (hint, it isn’t real and an artifact of the calculation) or the large MIN improvement (hint, even the author is skeptical of it).

If Pro Football Focus does another update after training camp then I’ll add it to the table.
