Says Pro Football Focus:

5. FLETCHER COX, EAGLES

Top 101 appearances: 5

There’s an argument to be made for Fletcher Cox having the very best second-best season of all time, and more people would be talking about his 2018 campaign if it weren’t for the sheer domination of Aaron Donald.

Cox ended the year ranked second among interior defenders with an overall grade of 92.5, and his 101 quarterback pressures were the most we’ve ever seen from a defensive tackle not named Donald.
