The fullback is a dinosaur position. I think we all know that by this point. The days of even Dan Kreider are long gone, and they will probably never return. But a recent graphic posted by Pro Football Focus really puts into focus just how much the position has shifted over the course of the past decade or so.
Back in 2006 players lined up at full back on over 13,000 snaps. Fast forward to 2017 and that number was just 4,000. pic.twitter.com/3IRA424lA0
The website began tracking data in 2006, and in their inaugural season compiling snap counts and positions, players lined up in a fullback position (not necessarily players who are designated as fullbacks) 13,450 times during the year.
