#17. Detroit Lions: Matthew Stafford & Theo Riddick
Stafford quietly enjoyed a strong season with the Lions in 2015. The former top overall pick set a career high in completion percentage (67.2 percent), and also had a passer rating of 97.0, his best mark since 2011. PFF grades Stafford poorly, however, as he ranks as the 26th-best quarterback in the league.
Riddick was Detroit’s fourth-leading rusher — behind Ameer Abdullah, Joique Bell and Stafford — but played the most snaps of any running back on the roster. The versatile third-year player finished third on the team with 80 receptions for 697 yards, and PFF gave him the third-highest grade of any running back in the league. We’re not convinced he’s quite at that level yet, but he certainly made a strong case for himself in 2015.
