Philadelphia Eagles quarterback Nick Foles was fantastic in 2013, completing 64% of his passes for a league-best 9.1 yards per attempt, 27:2 touchdown-to-interception ratio, and 119.2 passer rating. That passer rating remains the third-best mark in NFL history, behind only 2004 Peyton Manning (121.1) and 2011 Aaron Rodgers (122.5).
Foles was anything but great in the seasons that followed, playing below-average ball in 2014 before breaking his collar bone, getting traded to the St. Louis Rams to be the starter, being benched for some fella named Case Keenum that very season, asking for his release ahead of the 2016 season, and ultimately signing with the Chiefs to be Alex Smith’s back-up.
