For his career, Graham has converted just 10.7 percent of all of his pressures into sacks, says Pro Football Focus. The average NFL edge rusher this season converted 15.1 percent of his pressures into sacks, with Vic Beasley at an unsustainably high 28.6 percent.
Graham isn’t just a player that doesn’t convert as well as the best players in that regard (Von Miller was at 17.7 percent in 2016), but he consistently converts at a lower rate than average, which is certainly not a good thing. The key to his game, though, is in appreciating that as a flaw that keeps him from the Defensive Player of the Year conversation, but not ignoring the staggering rate of production he has in spite of that flaw.
Graham is one of the league’s most consistently productive edge rushers, well deserving of his place on the PFF All-Pro team this year and at number nine in the Top 101, and he still has a very clear aspect of his game he can work on to get even better. That should concern anybody tasked with blocking him in 2017 and beyond:
